Here's the thing. Wages would go down as much as the market for labor allows them to decrease. Artificially bolstering them inherently means there will be more under employment and unemployment. Who does that help?
Im fine with coming up with creative ways to help working class Americans share in the high productivity modern economy, such as an extension of the eitc or other "safety net" programs, but I don't think the one size fits all minimum wage approach is the right one.
And, it is mostly kids and young entrants who work for minimum wage (50% of those earning MW, even though though they comprise only 20% or the work force). Raising it will hurt them significantly.
Watch out, don't try to tell RB&B that its mostly kids and young entrants even though its true, or he'll admonish you to "step out into the real world."
