This is just something that came through my mind while I was sitting and playing games over the weekend.
The point of capitalism is to have workers working for just enough to 'pay the bills' (and sometimes not even that) but not enough to ever be able to stop working. Even what are considered to be 'good' jobs, ones that pay more than $20 an hour, still barely give you enough to save even in the cheapest parts of the US. That's not even counting that health insurance, 401K (why even bother as an hourly worker?), other investments and taxes are already taken out of every penny that you make, by both federal and most states, which reduces the amount of 'take-home' income that you have. So that $20 is more like $15 after taxes on the low end.
