Minimum Wage law is so stupid

Why do we continue to make laws that actually do more harm than good.
Take Minimum Wage. Do you realize that when Minimum Wage get forcibly raised, thousands of people lose their jobs, because the owners (mostly small businesses trying to make it) have to budget for it and can't afford to pay. Here in Arizona, they are repealing the wage rule for handicapped people. So, a class that had to be legislated to NOT be Discriminated against, were being fired first when the increase went into effect, but now can work for below minimum wage, in order to keep them on board. Stupid! Now they are cutting teenagers from jobs and giving more work to less people for no more pay-sound familiar?
Bottom line to voters: Don't legislate what people are getting paid. Let the market decide. If you don't like what your getting paid..quit or ask for a raise. If your valuable, they will pay, if not, it wasn't a job for you anyway. This will send a message that they need to pay more for good people. As long as people are happy working for a certain amount, companies will pay that certain amount. Don't force it because we ALL lose.
