Who is forcing them to work at Amazon? Their lives are clearly better working there than if Amazon had never existed. If conditions are so bad that these employees live in tents, why not quit and.... oh wait.... live in tents (now with less money).

Ah the old "it's better to have a glass of water and a stale breadcrust than eat nothing at all".

Amazon presumably. Without Amazon they would be making a living wage at a mom&pop store, and we would all be paying more for lower quality products with less choice.

Well, good luck with that.
