I was a college undergrad for years. So I moved around quite a lot, up to 0-4 times a year. Most of my roomies liked having me around; alas, that doesn't pay the bills.
Usually I couldn't afford to not live with my parents, not until the mid-1990s. Paying for a car and food and rent, let alone utilities, was just too much.
~ Income ~
For years, I earned Michigan's minimum wage, which was $3.35/hour from 1986 onward. I want to say until the 90s; FRED says it went up to $5.15 by 1998!
Not a living wage, most certainly.
(I'd been doing temp jobs from 1988-91, and in 1993, so my wages would've been higher. Probably as much as double. I clearly recall my final assignment in 2001 for Kelly Services. I said I could not afford to make only $9.00/hour for more than the fortnight* they claimed it'd last.)
