Emphasis mine. Places like WH worked on razor thin margins and made their money due to volume. When the prices went up, I found myself eating there less. Now the people who would have gladly worked for less than the Minimum Wage are now not working at all.

The minimum wage is simply another instance of the Government butting in to the free market. It would be like if, in an attempt to help the Big 3, the government put a minimum price of a car at $20k to raise auto company profits, you wouldn’t get more money to the auto makers on the low end, you would get fewer people buying.
