I never claimed that billions of people can live that way. I was merely responding to @FooBarBizBazz's comment above, pointing out that they can live that way if they really want to. There are others living that lifestyle voluntarily right now. Personally I think it would be miserable, but the option exists for those who really want it.

In developed countries at least, most labor is voluntary. There are certainly cases where people have been trafficked and essentially held as slaves, and we should do everything possible to stop those, but such cases are rare.
