..and if you had no car, no health insurance, no kids, and lived in a box. Yeah you can live the good life in the USA off $800 a month after taxes. The only people who claim that they "could" do this are the people who are not doing it.

I didn't have a car until I was 35. I didn't have health insurance until I was close to 40. I did not have any kids because I could barely afford to pay my own way. So what, exactly is your point? I wanted a better life so I worked hard for it and succeeded. QED.
