In an editorial at the Wall Street Journal, Daniel Klein explains that liberals/progressives have no real grasp of basic economics:

Zogby researcher Zeljka Buturovic and I considered the 4,835 respondents’ (all American adults) answers to eight survey questions about basic economics. We also asked the respondents about their political leanings: progressive/very liberal; liberal; moderate; conservative; very conservative; and libertarian.

Rather than focusing on whether respondents answered a question correctly, we instead looked at whether they answered incorrectly. A response was counted as incorrect only if it was flatly unenlightened.

Consider one of the economic propositions in the December 2008 poll: “Restrictions on housing development make housing less affordable.” People were asked if they: 1) strongly agree; 2) somewhat agree; 3) somewhat disagree; 4) strongly disagree; 5) are not sure.

Basic economics acknowledges that whatever redeeming features a restriction may have, it increases the cost of production and exchange, making goods and services less affordable. There may be exceptions to the general case, but they would be atypical.

Therefore, we counted as incorrect responses of “somewhat disagree” and “strongly disagree.” This treatment gives leeway for those who think the question is ambiguous or half right and half wrong. They would likely answer “not sure,” which we do not count as incorrect.

In this case, percentage of conservatives answering incorrectly was 22.3%, very conservatives 17.6% and libertarians 15.7%. But the percentage of progressive/very liberals answering incorrectly was 67.6% and liberals 60.1%. The pattern was not an anomaly.
[…]
How did the six ideological groups do overall? Here they are, best to worst, with an average number of incorrect responses from 0 to 8: Very conservative, 1.30; Libertarian, 1.38; Conservative, 1.67; Moderate, 3.67; Liberal, 4.69; Progressive/very liberal, 5.26.

Americans in the first three categories do reasonably well. But the left has trouble squaring economic thinking with their political psychology, morals and aesthetics.

Policies that liberals tend to support may help them win elections, but in action tend to hurt the economy or those they are intended to help.
