Lincoln vs Limbaugh, Ctd

Limbaugh asked who on earth came up with the idea of progressive taxation? In America, Lincoln established it. In theory, Adam Smith proposed it, as several readers have noted:

"It is not very unreasonable that the rich should contribute to the public expence, not only in proportion to their revenue, but something more than in proportion."

I'm sympathetic to Limbaugh's general argument - although I believe the debt and alarming inequality should temper one's preferences in this respect in the current circumstances. But it tells you something about today's "conservatism" that it is fiercely opposed to both Abraham Lincoln and Adam Smith on taxation and Friedrich von Hayek on universal health insurance.
