No, employers pay their employees whatever they can get away with. If they don't pay them enough, they go to a company that will more favourably pay them.
Your logic for opposing any sort of wage increase is flawed, especially after you so vigorously defended the tax rebate, or was that only because that was a Bush initative and this appears to be a Democratic one?
Higher pay = more money to spend = more goods and services bought = boost to economy.
