While I truly do sympathize with people who are trying to make ends meet, some work simply isn’t worth more than 5 bucks an hour. In a perfect world, people wouldn’t take the work unless it was worth their while, and the business would be forced by market forces to adjust their pay system accordingly. Obviously this isn’t a perfect world and that isn’t going to happen, but the solution still isn’t for the government to mandate that people must be paid 15 dollars an hour to flip burgers.
If they take the job it's worth their while by definition, no?
