The Place Where the Poor Once Thrived
A)This is the land of opportunity. If that weren’t already implied by the landscape-rolling green
hills palm trees, sun-kissed flowers-then it’s evident in the many stories of people who grew up
poor in these sleepy neighborhoods and rose to enormous success. People like Tri Tran, who
fled Vietnam on a boat in 1986, showed up in San Jose with nothing, made it to MIT, and then
founded the food-delivery start-up Munchery, which is valued at $ 300 million.
B)Indeed, data suggests that this is one of the best places to grow up poor in America. A child
born in the. early 1980s into a low-income family in San Jose had a 12.9 percent chance of
becoming a high earner as an adult, according to a landmark study released in 2014 by the
economist Raj Chetty and his colleagues from Harvard and Berkeley. That number--12.9
percent-may not seem remarkable, but it was: Kids in San Jose whose families fell in the bottom
quintile(五分位数)of income nationally had the best shot in the country at reaching the top
quintile.
C)By contrast, just 4.4 percent of poor kids in Charlotte moved up to the top; in Detroit the
figure was 5.5percent. San Jose had social mobility comparable to Denmark’s and Canada’s
and higher than other progressive cities such as Boston and Minneapolis.
D)The reasons kids in San Jose performed so well might seem obvious. Some of the world’s
most innovative companies are located here, providing opportunities such as the one seized by
a 12-year-old Mountain View resident named Steve Jobs when he called William Hewlett to
ask for spare parts and subsequently received a summer job. This is a city of immigrants-38
percent of the city’s population today is foreign-born-and immigrants and their children have
historically experienced significant upward mobility in America. The city has long had a large
foreign-born population (26.5 percent in1990), leading to broader diversity, which, the Harvard
and Berkeley economists say, is a good predictor of mobility.
E)Indeed, the streets of San Jose seem, in some ways, to embody the best of America. It’s
possible to drive in a matter of minutes from sleek(光亮的)office towers near the airport where
people pitch ideas to investors, to single-family homes with orange trees in their yards, or to a
Vietnamese mall. The libraries here offer programs in 17 languages, and there are areas filled
with small businesses owned by Vietnamese immigrants, Mexican immigrants, Korean
immigrants, and Filipino immigrants, to name a few.
F)But researchers aren’t sure exactly why poor kids in San Jose did so well. The city has a low
prevalence of children growing up in single-parent families, and a low level of concentrated
poverty, both factors that usually mean a city allows for good intergenerational mobility. But
San Jose also performs poorly on some of the measures correlated with good mobility. It is one
of the most unequal places out of the741 that the researchers measured, and it has high degrees
