Look at the tax returns of these people demanding raised minimum wage. And look at the refunds they get. Thousands of dollars in welfare for having kids they couldn't afford. The money is blown quickly. Big shopping spree since it's found money for them. Way more than they pay in.
If you divide that over the whole year, the minimum wage is already raised a pretty damn good bit. For people who suck at their jobs and are just in the way. If you want food or your groceries scanned and bagged, unless you're stupid as hell you can do it faster and better than these minimum wagers.
