Alright so lets go through the consequences of what happens when the minimum wage is raised. Wal-Mart will then have to start paying more to it's employees. Wal-Mart will also raise it's prices to keep the profit margin constant, go to make a buck you know. At that point in time, all the people who work at Wal-Mart will start paying more for all the things they also buy from Wal-Mart, and they will be just as poor after the minimum wage hike as they were before.
Secondly, I will get screwed because my prices at Wal-Mart will also go up, but my wages won't.
