The OP made a good point that applies to all poor countries I've lived in: those jobs are the only (even the best) way out for most people to get out of poverty, which they do to help their families/children/themselves.
Maybe you were raised in a family that did not need to go through such hard labor, but that doesn't mean your right in your view of your own world ;)
P.S. I was also born and raised in a poor country.
That being said I do agree that our attitude of "lets shut down here cuz it doesnt work for us" does more harm than good. It's not like this will solve corruption. If anything, this will give Chinese people more reason to hate on USA and India, thus further cementing their governments power.
This is true of most strict rules elsewhere: they're there but seldom enforced. Take speed limits, they're strict, but good luck enforcing them. All we do is we monitor from time to time and give tickets. Yet we could enforce this to the manufacturers, right? Why can a car go beyond the speed limit if it's strictly prohibited?
We cannot compare working conditions as is, but they're easy to compare when you take time into account: how where our labor laws a couple of generations ago? Not that different than poor countries today.
