Who actually gets paid only minumum wage?
I live in a major metro area and even the fast food places are paying more than minumum wage.
The minimum wage ends up affecting prices everywhere. Few people are going to take unpleasant jobs for minimum wage when more pleasant ones are available. Even when there aren't official "pegs" (exist in union contracts), in many fields baseline wages are effectively pegged to be a certain amount above minimum in order to attract workers.
I wish people would acknowledge the real effect of the minimum wage: to make unemployable people whose skills don't justify paying that much; to the extent that other people's wages go up, it's a result of the less-skilled workers being removed from the market.
