Wages in the fast-food industry have stayed low for two basic reasons. First, many are low-skill service jobs in an efficient assembly where workers are easily replaced and don’t require much education. Second, there is a large supply of people who are willing to make cheap burgers at a low wage. It is easy to look at this scenario and conclude, “well, economics determines prices and wages, and that’s that.” But the full story is more complicated. Cheap fast food and their cheap workers impose a cost on the country in the form of food stamps, welfare through the tax code, and social safety net programs. This is a place for government to intervene — and for corporations to sacrifice some of their profits — by raising wages to a livable level.
