40 years ago the super-major purchases that an affluent family might make in China, would be a bicycle, a radio, and a desk.
Today (thanks to assembly shops like Foxconn) the standard of living has been raised so that those lucky enough to get employment at a place like Foxconn, can often buy a car, a computer, and a TV.
Every major city in China is building hundreds (and I'm not kidding, HUNDREDS, it is astonishing) of skyscrapers on its edges to accomodate rural, farm poor folks who are moving to the city to get jobs at place like Foxconn.
That doesn't mean that everything is always on the level or that Foxconn is pure at heart. Far from it, corruption is widespread and so many of the jobs are incredibly dangerous. But construction work is far and away the most dangerous work environment in China today.
