Paul Krugman: Voodoo Health Economics

Elizabeth Edwards has cancer. John McCain has had cancer in the past. Last weekend, Mrs. Edwards bluntly pointed out that neither of them would be able to get insurance under Mr. McCain’s health care plan.

It’s about time someone said that and, more generally, made the case that Mr. McCain’s approach to health care is based on voodoo economics — not the supply-side voodoo that claims that cutting taxes increases revenues (though Mr. McCain says that, too), but the equally foolish claim, refuted by all available evidence, that the magic of the marketplace can produce cheap health care for everyone.
