The World Might Be Running Low on Americans


The world has been stricken by scarcity. Our post-pandemic pantry has run bare of gasoline, lumber, microchips, chicken wings, ketchup packets, cat food, used cars and Chickfil-A sauce. Like the Great Toilet Paper Scare of 2020, though, many of these shortages are the consequence of near-term, Covid-related disruptions. Soon enough there will again be a chicken wing in every pot and more than enough condiments to go with it.


But there is one recently announced potential shortage that should give Americans great reason for concern. It is a shortfall that the nation has rarely had to face, and nobody quite knows how things will work when we begin to run out.


I speak, of course, of all of us: The world may be running low on Americans — most crucially, tomorrow’s working-age, childbearing, idea-generating, community-building young Americans. Late last month, the Census Bureau released the first results from its 2020 count, and the numbers confirmed what demographers have been warning of for years: The United States is undergoing “demographic stagnation,” transitioning from a relatively fast-growing country of young people to a slow-growing, older nation.


Many Americans might consider slow growth a blessing. Your city could already be packed to the gills, the roads clogged with traffic and housing prices shooting through the roof. Why do we need more folks? And, anyway, aren’t we supposed to be conserving resources on a planet whose climate is changing? Yet demographic stagnation could bring its own high costs, among them a steady reduction in dynamism, productivity and a slowdown in national and individual prosperity, even a diminishment of global power.


And there is no real reason we have to endure such a transition, not even an environmental one. Even if your own city is packed like tinned fish, the U.S. overall can accommodate millions more people. Most of the counties in the U.S. are losing working-age adults; if these declines persist, local economies will falter, tax bases will dry up, and localgovernments will struggle to maintain services. Growth is not just an option but a necessity — it’s not just that we can afford to have more people, it may be that we can’t afford not to.


But how does a country get more people? There are two ways: Make them, and invite them in. Increasing the first is relatively difficult — birthrates are declining across the world, and while family-friendly policies may be beneficial for many reasons, they seem to do little to get people to have more babies. On the second method, though, the United States enjoys a significant advantage — people around the globe have long been clamoring to live here, notwithstanding our government’s recent hostility to foreigners. This fact presents a relatively simple policy solution to a vexing long-term issue: America needs more people, and the world has people to send us. All we have to do is let more of them in.


For decades, the United States has enjoyed a significant economic advantage over other industrialized nations — our population was growing faster, which suggested a more youthful and more prosperous future. But in the last decade, American fertility has gone down. At the same time, there has been a slowdown in immigration.


The Census Bureau’s latest numbers show that these trends are catching up with us. As of April 1, it reports that there were 331,449,281 residents in the United States, an increase of just 7.4 percent since 2010 — the second-smallest decade-long growth rate ever recorded, only slightly ahead of the 7.3 percent growth during the Depression-struck 1930s.


The bureau projects that sometime next decade — that is, in the 2030s — Americans over 65 will outnumber Americans younger than 18 for the first time in our history. The nation will cross the 400-million population mark sometime in the late 2050s, but by then we’ll be quite long in the tooth — about half of Americans will be over 45, and one fifth will be older than 85.


The idea that more people will lead to greater prosperity may sound counterintuitive — wouldn’t more people just consume more of our scarce resources? Human history generally refutes this simple intuition. Because more people usually make for more workers, more companies, and most fundamentally, more new ideas for pushing humanity forward, economic studies suggest that population growth is often an important catalyst of economic growth.


A declining global population might be beneficial in some ways; fewer people would most likely mean less carbon emission, for example — though less than you might think, since leading climate models already assume slowing population growth over the coming century. And a declining population could be catastrophic in other ways. In a recent paper, Chad Jones, an economist at Stanford, argues that a global population decline could reduce the fundamental innovativeness of humankind. The theory issimple: Without enough people, the font of new ideas dries up, Jones argues; without new ideas, progress could be imperiled.


There are more direct ways that slow growth can hurt us. As a country’s population grows heavy with retiring older people and light with working younger people, you get a problem of too many eaters and too few cooks. Programs for seniors like Social Security and Medicare may suffer as they become dependent on ever-fewer working taxpayers for funding. Another problem is the lack of people to do all the work. For instance, experts predict a major shortage of health care workers, especially home care workers, who will be needed to help the aging nation.


In a recent report, Ali Noorani, the chief executive of the National Immigration Forum, an immigration-advocacy group, and a co-author, Danilo Zak, say that increasing legal immigration by slightly more than a third each year would keep America’s ratio of working young people to retired old people stable over the next four decades.


As an immigrant myself, I have to confess I find much of the demographic argument in favor of greater immigration quite a bit too anodyne. Immigrants bring a lot more to the United States than simply working-age bodies for toiling in pursuit of greater economic growth. I also believe that the United States’ founding idea of universal equality will never be fully realized until we recognize that people outside our borders are as worthy of our ideals as those here through an accident of birth.

A partir de uma análise da conjuntura geopolítica global recente, relacione corretamente os casos de conflitos armados interculturais, religiosos e territoriais aos diferentes países onde se manifestam, numerando os parênteses abaixo de acordo com a seguinte indicação:

1. Nigéria;

2. Israel;

3. Mianmar;

4. Síria.

( ) O país já registra mais de 380 mil mortes oficiais no pior conflito de sua história, iniciado em 2011, na esteira da Primavera Árabe. O conflito opõe o governo liderado por Bashar Al-Assad, cuja família, desde a década de 1970, comanda o país por meio de um brutal regime de partido único, contra o qual pelejam forças sunitas para a derrubada da ditadura de Assad. A partir de 2013, o grupo terrorista Estado Islâmico (EI) aproveitou-se da situação de caos criada pela guerra civil e, vindo do Iraque, avançou de forma avassaladora, ocupando metade do território do país, espalhando ondas de ataques que se intensificaram ao longo da década passada.

( ) Movido pelo apelo religioso de retorno à “Terra Prometida”, o movimento sionista que surgiu no final do século XIX, propunha construir colônias no território previamente ocupado por um povo que havia aí se estabelecido há mais de 12 séculos, contando, na época, o território em disputa, com mais de 1,2 milhão de árabes. O país foi oficialmente criado no ano de 1948 e, desde então, uma série de disputas territoriais, com centenas de milhares de mortos, vêm ocorrendo entre os dois lados do conflito.

( ) O grupo armado radical islâmico denominado Boko Haram, um dos maiores da atualidade, combate, com atos terroristas, a influência ocidental no país, enquanto defende a implantação radical da lei islâmica, a sharia, e a construção de uma república fundamentalista islâmica no país. Estima-se que o grupo já tenha executado mais de três mil pessoas,concentrando sua ação sobretudo na porção norte do país.

( ) O assassinato a tiros de mais de 100 manifestantes contrários ao recente golpe militar gerou grande indignação internacional, levando ministros da Defesa de 12 países a fazer duras críticas aos militares que estão no comando daquele país. Por meio desse golpe, os militares tomaram o controle do país após uma eleição em que o partido Liga Nacional para a Democracia (NLD), liderado por Aung San Suu Kyi, venceu com uma vitória esmagadora. Mais de 400 pessoas já foram executadas na repressão aos protestos ao governo desde o golpe.

The World Might Be Running Low on Americans


The world has been stricken by scarcity. Our post-pandemic pantry has run bare of gasoline, lumber, microchips, chicken wings, ketchup packets, cat food, used cars and Chickfil-A sauce.

The Census Bureau’s latest numbers show that these trends are catching up with us. As of April 1, it reports that there were 331,449,281 residents in the United States, an increase of just 7.4 percent since 2010 — the second-smallest decade-long growth rate ever recorded, only slightly ahead of the 7.3 percent growth during the Depression-struck 1930s.


The bureau projects that sometime next decade — that is, in the 2030s — Americans over 65 will outnumber Americans younger than 18 for the first time in our history. The nation will cross the 400-million population mark sometime in the late 2050s, but by then we’ll be quite long in the tooth — about half of Americans will be over 45, and one fifth will be older than 85.


The idea that more people will lead to greater prosperity may sound counterintuitive — wouldn’t more people just consume more of our scarce resources? Human history generally refutes this simple intuition. Because more people usually make for more workers, more companies, and most fundamentally, more new ideas for pushing humanity forward, economic studies suggest that population growth is often an important catalyst of economic growth.


A declining global population might be beneficial in some ways; fewer people would most likely mean less carbon emission, for example — though less than you might think, since leading climate models already assume slowing population growth over the coming century. And a declining population could be catastrophic in other ways. In a recent paper, Chad Jones, an economist at Stanford, argues that a global population decline could reduce the fundamental innovativeness of humankind. The theory issimple: Without enough people, the font of new ideas dries up, Jones argues; without new ideas, progress could be imperiled.


There are more direct ways that slow growth can hurt us. As a country’s population grows heavy with retiring older people and light with working younger people, you get a problem of too many eaters and too few cooks. Programs for seniors like Social Security and Medicare may suffer as they become dependent on ever-fewer working taxpayers for funding. Another problem is the lack of people to do all the work. For instance, experts predict a major shortage of health care workers, especially home care workers, who will be needed to help the aging nation.


In a recent report, Ali Noorani, the chief executive of the National Immigration Forum, an immigration-advocacy group, and a co-author, Danilo Zak, say that increasing legal immigration by slightly more than a third each year would keep America’s ratio of working young people to retired old people stable over the next four decades.


As an immigrant myself, I have to confess I find much of the demographic argument in favor of greater immigration quite a bit too anodyne. Immigrants bring a lot more to the United States than simply working-age bodies for toiling in pursuit of greater economic growth. I also believe that the United States’ founding idea of universal equality will never be fully realized until we recognize that people outside our borders are as worthy of our ideals as those here through an accident of birth.

Leia o fragmento, a seguir, retirado do livro Clara dos Anjos, de Lima Barreto, e responda à questão.


Cassi Jones, sem mais percalços, se viu lançado em pleno Campo de Sant’Ana, no meio da multidão que jorrava das portas da Catedral, cheia da honesta pressa de quem vai trabalhar. A sua sensação era que estava numa cidade estranha. No subúrbio tinha os seus ódios e os seus amores; no subúrbio, tinha os seus companheiros, e a sua fama de violeiro percorria todo ele, e, em qualquer parte, era apontado; no subúrbio, enfim, ele tinha personalidade, era bem Cassi Jones de Azevedo; mas, ali, sobretudo do Campo de Sant’Ana para baixo, o que era ele? Não era nada. Onde acabavam os trilhos da Central, acabava a sua fama e o seu valimento; a sua fanfarronice evaporava-se, e representava-se a si mesmo como esmagado por aqueles “caras” todos, que nem o olhavam. [...]

Na “cidade”, como se diz, ele percebia toda a sua inferioridade de inteligência, de educação; a sua rusticidade, diante daqueles rapazes a conversar sobre cousas de que ele não entendia e a trocar pilhérias; em face da sofreguidão com que liam os placards dos jornais, tratando de assuntos cuja importância ele não avaliava, Cassi vexava-se de não suportar a leitura; comparando o desembaraço com que os fregueses pediam bebidas variadas e esquisitas, lembrava-se que nem mesmo o nome delas sabia pronunciar; olhando aquelas senhoras e moças que lhe pareciam rainhas e princesas, tal e qual o bárbaro que viu, no Senado de Roma, só reis, sentia-se humilde; enfim, todo aquele conjunto de coisas finas, de atitudes apuradas, de hábitos de polidez e urbanidade, de franqueza no gastar, reduziam-lhe a personalidade de medíocre suburbano, de vagabundo doméstico, a quase cousa alguma.

Com base no trecho e no romance, acerca das relações entre personagens e os estilos de época, considere as afirmativas a seguir.


I. Clara, ao nutrir ilusões quanto às intenções amorosas de Cassi, aproxima-se da condição sonhadora de personagens femininas românticas.

II. Clara, ao entregar-se a Cassi e ao ceder às suas investidas sexuais, exibe a dificuldade de resistir aos instintos, como ocorre com personagens femininas naturalistas.

III. Cassi, ao recorrer a falsas promessas e fugir das responsabilidades com Clara, destoa da caracterização afetiva e moral dos heróis masculinos românticos.

IV. Cassi, ao compreender a complexidade das injustiças sociais que se abatem contra ele e os demais suburbanos, acirra o espírito combativo, assim como os heróis modernistas.

Leia o trecho, a seguir, retirado do livro Quarenta dias, de Maria Valéria Rezende, e responda à questão.


Saí, em busca de Cícero Araújo ou sei lá de quê, mas sem despir-me dessa nova Alice, arisca e áspera, que tinha brotado e se esgalhado nesses últimos meses e tratava de escamotear-se, perder-se num mundo sem porteira, fugir ao controle de quem quer que fosse. Tirei o interfone do gancho e o deixei balançando, pendurado no fio, bati a porta da cozinha e desci correndo pela escada de serviço, esperando que o porteiro se enfiasse na guarita pra responder ao interfone de frente pro saguão, de modo que eu pudesse sair de fininho, por trás dos pilotis, e escapar sem ser vista. Não me importava nada o que haveria de acontecer com o interfone nem com o porteiro.

Ganhei a rua e saí a esmo, querendo dar o fora dali o mais depressa possível, como se alguém me vigiasse ou me perseguisse, mas saí andando decidida, como se soubesse perfeitamente aonde ia, pisando duro, como nunca tinha pisado em parte alguma da minha antiga terra, lá onde eu sempre soube ou achava que sabia que rumo tomar. Saí, sem perguntar nada ao guri da banca da esquina nem a ninguém, até que me visse a uma distância segura daquele endereço que me impingiram e onde eu me sentia espionada, sabe-se lá que raio de combinação eles tinham com os porteiros, com os vizinhos? Olhe só, Barbie, como eu chegava perigosamente perto da paranoia e ainda falo “deles” como se fossem meus inimigos, minha filha e meu genro

REZENDE, Maria Valéria. Quarenta dias. 1ª ed. Rio de Janeiro: Objetiva, 2014. p. 95-96.

Com base no trecho e no romance, considere as afirmativas a seguir acerca da narradora.


I. No trecho “... esperando que o porteiro se enfiasse na guarita pra responder ao interfone de frente pro saguão...”, apesar de a narradora estar em primeira pessoa, assim como no restante do romance, ela é também onisciente no contato com diversas personagens.

II. A narradora alterna passagens que contêm o relato das próprias ações, como em “Tirei o interfone do gancho e o deixei balançando, pendurado no fio, bati a porta da cozinha e desci correndo pela escada de serviço...”, com trechos que são suposições dos atos de personagens.

III. Há momentos no trecho dedicados à expressão de sentimentos provocados pelas próprias ações da narradora-protagonista, como em: “Não me importava nada o que haveria de acontecer com o interfone nem com o porteiro.”

IV. O trecho apresenta passagens em que a narradora-protagonista faz conjecturas sobre conspirações armadas por outras personagens, como em: “... sabe-se lá que raio de combinação eles tinham com os porteiros, com os vizinhos?”

The World Might Be Running Low on Americans


The world has been stricken by scarcity. Our post-pandemic pantry has run bare of gasoline, lumber, microchips, chicken wings, ketchup packets, cat food, used cars and Chickfil-A sauce. Like the Great Toilet Paper Scare of 2020, though, many of these shortages are the consequence of near-term, Covid-related disruptions. Soon enough there will again be a chicken wing in every pot and more than enough condiments to go with it.


But there is one recently announced potential shortage that should give Americans great reason for concern. It is a shortfall that the nation has rarely had to face, and nobody quite knows how things will work when we begin to run out.


I speak, of course, of all of us: The world may be running low on Americans — most crucially, tomorrow’s working-age, childbearing, idea-generating, community-building young Americans. Late last month, the Census Bureau released the first results from its 2020 count, and the numbers confirmed what demographers have been warning of for years: The United States is undergoing “demographic stagnation,” transitioning from a relatively fast-growing country of young people to a slow-growing, older nation.


Many Americans might consider slow growth a blessing. Your city could already be packed to the gills, the roads clogged with traffic and housing prices shooting through the roof. Why do we need more folks? And, anyway, aren’t we supposed to be conserving resources on a planet whose climate is changing? Yet demographic stagnation could bring its own high costs, among them a steady reduction in dynamism, productivity and a slowdown in national and individual prosperity, even a diminishment of global power.


And there is no real reason we have to endure such a transition, not even an environmental one. Even if your own city is packed like tinned fish, the U.S. overall can accommodate millions more people. Most of the counties in the U.S. are losing working-age adults; if these declines persist, local economies will falter, tax bases will dry up, and localgovernments will struggle to maintain services. Growth is not just an option but a necessity — it’s not just that we can afford to have more people, it may be that we can’t afford not to.


But how does a country get more people? There are two ways: Make them, and invite them in. Increasing the first is relatively difficult — birthrates are declining across the world, and while family-friendly policies may be beneficial for many reasons, they seem to do little to get people to have more babies. On the second method, though, the United States enjoys a significant advantage — people around the globe have long been clamoring to live here, notwithstanding our government’s recent hostility to foreigners. This fact presents a relatively simple policy solution to a vexing long-term issue: America needs more people, and the world has people to send us. All we have to do is let more of them in.


For decades, the United States has enjoyed a significant economic advantage over other industrialized nations — our population was growing faster, which suggested a more youthful and more prosperous future. But in the last decade, American fertility has gone down. At the same time, there has been a slowdown in immigration.

O crescimento exponencial das tecnologias comunicacionais e informacionais embasadas na rede mundial de computadores implica consideráveis influências no desenvolvimento da economia global e, assim, das sociedades contemporâneas. Conforme o sociólogo espanhol, Manuel Castells, a economia mundial deixou para trás a Era Industrial e adentrou na Era da Informação. Para este cientista social, as pessoas, em muitos âmbitos de suas vidas e relações sociais cotidianas, estão atualmente inseridas no que ele chama de “Sociedade em Rede”.
Avalie as seguintes afirmações sobre as características dessa “Sociedade em Rede”:
I. As pessoas, empresas e Estados estão, cada vez mais, interconectados e suas ações não estão restritas por distâncias espaciais e fronteiras territoriais. II. Os parques industriais se fortaleceram nos países em desenvolvimento econômico regidos pelas novas tecnologias de informação e comunicação. III. As novas tecnologias de informação e comunicação possibilitaram a interação interpessoal e a taxação internacional das grandes corporações do capitalismo. IV. Não há um “centro” informacional, mas uma série intrincada de “nódulos” de informações que fazem a Rede tanto existir como operar com maior liberdade.
