Doesn't matter to your point. You're arguing that pressure to keep employees will lead employers to raise wages or the employees will walk. I'm saying that in the real world, even in time of full employment when workers enjoy more mobility, that doesn't happen. In constant dollars, wages have been in decline the early 1960s. Where the money comes from is irrelevant.
Would you favor a law in conjunction with 9-9-9 that mandates the employer passing that savings to employees in the form of wage increases?
