> The people working in those deplorable conditions are doing so voluntarily, right?
They actually are, and if you ask them then can explain why they chose it. These factory jobs are usually very sought after, and has lifted millions from extreme poverty. I suspect you have little idea how harsh third world poverty actually is.

> Just like the homeless guy digging through the trash on Market St in San Francisco has the choice to not be homeless
That's very different. He can choose whether to dig for trash, but not directly whether to be homeless. You can choose your actions, but not end results.
He is also fairly likely to be mentally incapable to make rational decisions. Meanwhile, the Asian factory workers you mention are quite capable and responsible adults. As are the vast majority of American Uber drivers.
