Raising the minimum wage raises the floor price above the free-market price, you get unemployment of the least skilled. Per Wikipedia:
An example of a price floor is minimum wage laws; in this case, employees are the suppliers of labor and the company is the consumer. When the minimum wage is set above the equilibrium market price for unskilled labor, unemployment is created (more people are looking for jobs than there are jobs available). A minimum wage above the equilibrium wage would induce employers to hire fewer workers as well as allow more people to enter the labor market; the result is a surplus in the amount of labor available. However, workers would have higher wages. The equilibrium wage for workers would be dependent upon their skill sets along with market conditions.[2]
With the progressives’ feel-good economics, they end up putting people out of work who need the most help getting jobs: the unskilled, the young, and the minorities.
