Mark Perry points out that relatively few workers make the minimum wage:
The notion that there are millions of full-time workers struggling to raise a family, but are stuck in jobs paying the minimum wage for long periods of time is more myth than fact. Almost all full-time workers (99.4%) are earning more than the minimum wage, and almost all full-time hourly workers (98.3%) are earning more than the minimum wage. Most importantly, the fact that more than three out of four teenagers (77.2%), who are the least skilled and least educated group of workers, earned more than the minimum wage in 2011 would suggest the minimum wage is mostly an entry-level wage for beginning workers with no skills. The reality of the labor market is that even a large majority of previously unskilled teenage workers are earning more than the minimum wage as soon as they acquire minimal jobs skills and work habits, and can demonstrate their value to employers.
