I worked for minimum wage when I was 16. And then, only for 3 month or so, until I got my first review. At a fast food joint.
I was on my own, paying all my own bills by the time I was 18 (not by choice, but both parents had passed away). I worked fuill time, went to school full time (and I got more than minimum wage, and *gasp* also had health insurance offered through my job...at a convenience store!).
I had a room mate. I ate mac and cheese and eggs more times that I would care to count.
I didn't have cable, or internet, or a shiny new car, or cell phone or anything. I didn't have time to need any of those things.
But guess what, that life only lasted for about 4 years, until I got out of school.
A minimum wage job is not meant to be a lifestyle...only a total loser stays at minimum wage for an extended period of time.
