What is the problem were trying to solve? Is it the economy - or is it the fact that Democrats demagogue the minimum wage?" Strictly as a political matter, indexing would, theoretically, take the minimum wage" off the table. But only theoretically, since in reality there is no way you can prevent complainers from demanding more.Minimum wage belongs in scare quotes because it is actually a productivity threshold rule for employers.

Thomas Sowell favored the minimum wage in his callow youth - but ultimately he analyzed its actual effect. And then he looked at history, and found out that its actual effect was indeed its intended effect - namely, to price less skilled blacks out of the job market, keeping them from competing with whites for jobs.
In reality it was started explicitly as anti-black legislation. And the beauty of it - from the Democrat political perspective - is that it tickles the fancy of the very people whose prospects it subverts.
