It's all about economics. Raise the price of anything and the demand goes down. Raise the price of labor and the demand for labor decreases. It also adds to inflation, because the higher costs of labor get passed to the consume. Then, the people who just got a pay raise from raising the minimum wage are suddenly back where they started. It's like one step forward, two steps back.
The minimum wage should be abolished! I'm sorry Romney doesn't feel the same way, but it's either him or Obama, take your pick. Me, I'm sticking with Romney.
