NATIONAL HEALTHCARE….Tyler Cowen writes:

Since single-payer national health insurance violates every economic law known to mankind, I am again unsure how I could leap on the Democratic bandwagon.

But every developed country except the United States has a national health insurance plan, right? And they mostly seem to work pretty well, don’t they?

So either they don’t violate every economic law known to mankind, or else economists are doing a pretty dismal job of adducing economic laws. Which is it?
