Still, the tea parties are not based on the cold wonkery of budget data. They are based on an “ethical populism.” The protesters are homeowners who didn’t walk away from their mortgages, small business owners who don’t want corporate welfare and bankers who kept their heads during the frenzy and don’t need bailouts. They were the people who were doing the important things right — and who are now watching elected politicians reward those who did the important things wrong.

Voices in the media, academia, and the government will dismiss this ethical populism as a fringe movement — maybe even dangerous extremism. In truth, free markets, limited government, and entrepreneurship are still a majoritarian taste. In March 2009, the Pew Research Center asked people if we are better off “in a free market economy even though there may be severe ups and downs from time to time.” Fully 70% agreed, versus 20% who disagreed.

Free enterprise is culturally mainstream, for the moment. Asked in a Rasmussen poll conducted this month to choose the better system between capitalism and socialism, 13% of respondents over 40 chose socialism. For those under 30, this percentage rose to 33%. (Republicans were 11 times more likely to prefer capitalism than socialism; Democrats were almost evenly split between the two systems.)

The way I put it is that “capitalism” is merely the economic term of art for “freedom”.
