This is the problem. Everyone working 40 hours per week deserves a living wage, whether they're fresh out of high school or 8 years into a humanities degree. There's this weird sense out there that working in food service isn't a "real job," or as you say they haven't started their "career." This is how you end up with people working 60 or 80 hour work weeks, or two or three jobs, to provide for themselves and their family. Every 40 hour job is a "real job" and deserves a living wage. Otherwise you're just making people depend on our social safety net, and no one wants that.
