Disparity in life spans of the rich and the poor is growing
Sabrina Tavernise
February 12, 2016

Experts have long known that rich people generally
live longer than poor people. But a growing body of data
shows a more disturbing pattern: Despite big advances
in medicine, technology and education, the longevity gap
between high-income and low-income Americans has been
widening sharply.
The poor are losing ground not only in income, but also
in years of life, the most basic measure of well-being. In the
early 1970s, a 60-year-old man in the top half of the earnings
ladder could expect to live 1.2 years longer than a man of
the same age in the bottom half, according to an analysis
by the Social Security Administration. Fast-forward to 2001,
and he could expect to live 5.8 years longer than his poorer
counterpart.
New research released this month contains even more
jarring numbers. Looking at the extreme ends of the income
spectrum, economists at the Brookings Institution found that
for men born in 1920, there was a six-year difference in life
expectancy between the top 10 percent of earners and the
bottom 10 percent. For men born in 1950, that difference had
more than doubled, to 14 years. For women, the gap grew to
13 years, from 4.7 years. “There has been this huge spreading
out,” said Gary Burtless, one of the authors of the study.
The growing chasm is alarming policy makers, and has
surfaced in the presidential campaign. During a Democratic
debate, Senator Bernie Sanders and Hillary Clinton expressed
concern over shortening life spans for some Americans. “This
may be the next frontier of the inequality discussion,” said
Peter Orszag, a former Obama administration official now at
Citigroup, who was among the first to highlight the pattern.
The causes are still being investigated, but public health
researchers say that deep declines in smoking among the
affluent and educated may partly explain the difference.
Overall, according to the Brookings study, life expectancy
for the bottom 10 percent of wage earners improved by just
3 percent for men born in 1950 compared with those born
in 1920. For the top 10 percent, though, it jumped by about
28 percent. (The researchers used a common measure – life
expectancy at age 50 – and included data from 1984 to 2012.)

Gabarito comentado

É necessário responder a quem se refere o trecho “some americans" na frase: “shortening life spans for some Americans". Em português, “encurtamento da expectativa de vida para alguns americanos".
A partir da leitura do texto, compreende-se que a pesquisa comprovou que a expectativa de vida de ricos é superior a dos pobres e que a distância entre as expectativas de um e de outro está aumentando. A partir deste entendimento é possível concluir que o encurtamento da expectativa de vida de alguns americanos só pode referir-se aos americanos mais pobres já que, segundo a pesquisa, são eles que tem a menor expetativa de vida.
Vejamos, então, as alternativas:
Alternativa A.
A alternativa está INCORRETA pois a expectativa de vida dos americanos mais ricos está aumentando.
Alternativa B.
O último parágrafo do texto informa que os dados usados na pesquisa usaram como medida comum a expectativa de vida aos 50 anos e não aos 14 anos. A alternativa B está ERRADA.
Alternativa C.
Esta é a resposta CORRETA, pois, como vimos acima, o encurtamento da expectativa de vida de alguns americanos só pode referir-se aos americanos mais pobres já que, segundo a pesquisa reportada no texto, são eles que têm a menor expectativa de vida
Alternativa D.
Pelo contrário, pesquisadores em saúde pública apontam a redução do tabagismo dentre os mais ricos e instruídos como um possível fator que contribui parcialmente para a diferença entre a expectativa de vida entre ricos e pobre. Ou seja, parar de fumar prolonga a vida, não a reduz. A alternativa D está INCORRETA.
Alternativa E.
No texto inteiro, a única menção ao nível de instrução se dá na menção a hipótese levantada pelos pesquisadores em saúde pública de que a redução do tabagismo entre os ricos e mais instruídos justificaria, em parte, o aumento da diferença de expectativa de vida. Conclui-se, pois, que americanos com maior nível de escolaridade estão entre aqueles de maior renda e, portanto, vivem mais. A alternativa E está INCORRETA.
RESPOSTA: C
