When I was younger I had a lot of friends that were making minimum wage as cooks or whatever in Boston. They (and me) had plenty of money to spend on alcohol, weed, bars, pizza, etc. If anyone had wanted to, they could have made sacrifices and put away over $250 a month.
Of course, things are a little different when you have a family, but then again, in my opinion, you shouldn't have a family until you're financially stable.
I know live in Tanzania and the situation is so different that I find it ridiculous when people in America complain about income inequality or the lack of a "living wage."
Even the poorest employed people in America are far better off than most of the people here, and if you told them about how the so called "poorest" in America live, they would literally kill to switch places with them.
