It does not bother me to read [Paul] Krugman's anti-Republican rants. What does bother me is that the man pretends to be something he clearly is not: an economist.
That is correct. Let me say it again. Paul Krugman is not an economist. His colleagues in the economics profession and the editorial board of the Times may call him an economist, but that does not make him one.
This is harsh criticism, I realize, so I must explain my views in full. Yes, Krugman has a Ph.D. from MIT in economics, but his writings, both popular and academic, demonstrate that he does not believe in laws of economics. Instead, like most folks with socialist leanings, he believes that the state is both omniscient and omnipotent and simply by fiat can eliminate those pesky little problems caused by scarcity.
