It seems to me that working retail has gotten a lot worse since the recession. I worked retail after high school before deciding to go to college, and then worked the same job on summers home from school. What was interesting was that between when I started that job in 2005 and when I left for the final time in 2010, my coworkers went from being mostly high school and college kids to all sorts of folks of varying age…
I think a lot of people could live OK in the Midwest on $10 / hour.
I wish more people would move away from the super high cost of living areas (California, New England, ...etc) and "vote with their feet" so to speak. If 10% of the populations of Cali and Massachusetts moved inward, I think that would drive house prices down and wages up. All the rich people are still around to buy stuff and no poor people left to work retail.
