That is an argument that has been made again and again. Foxconn is actually a very sought after employer, as the others are often much worse. Standards vary, unfortunately. But if you have read Das Kapital and its descriptions of the horrors of Manchester capitalism, you have to conclude that it was actually worse in Europe not so long ago. And like Europe, China will rise to better living conditions. It just takes a while.

Of course, protesting against the worst outliers is still a worthwhile and noble cause!
