besides making the cost of everything go up, raising the minimum wage for the dumbest of the dumb devalues every actually good employee you have.
As the salary of the minimum wage idiots creeps up... it starts getting closer and closer to the salaries of your low level managers. So why strive to become a manager and deal with all the stress when you can just sort of push a mop and make almost as much.
the mentality that says "I'll just push a mop because I can do that and make as much money my boss"... that's the mentality that works for minimum wage. There's no fixing that no matter what you pay them. You pay them less... they're still gonna work for minimum wage. You pay em more... they're still gonna work for minimum wage.
