Don Boudreaux thinks that most are no better than con men. Here’s a letter of his to the New York Post:

Editor, The New York Post

Dear Editor:

Richard Epstein explains how the “Employee Free Choice Act,” supported by Sen.
Obama, will impose especially large burdens on small businesses – a fact at odds
with Sen. Obama’s pledge to promote such enterprises (“A Labor Dilemma for
President Bam,” Oct. 21). By raising employers’ costs of hiring American
workers, this Act will also increase off-shoring, another phenomenon that Sen.
Obama loudly deplores.

The general lesson here is that politicians are akin to faith-healers. Both
pose as wizards reciting crackpot recipes with charming words. The faith-healer
dupes his customers into believing that he will suspend medical reality; the
politician dupes voters into believing that he will suspend economic reality.
Both are frauds.

Sincerely,
Donald J. Boudreaux
