Minimum wage jobs are just that. Supplemental income jobs, jobs for high school kids and college kids working to earn a few bucks. They are not and have never been meant to provide wages sufficient to provide for a family, nor should they. Perhaps if people really cared about those things there would be a greater emphasis on creating more industry and real middle income jobs, not trying to fix the economy and employment situation by a career as a fry cook.
