International Trade---An Idiot's perspective

Some liberals adhere to Krugman as their intellectual backbone---after all, they feel their points are backed up by a Nobel-winning economist. However, it is recently reviewed that some of them completely ignore Krugman's insight that won him the Nobel Prize--why people trade. Krugman gave a clear answer to the benefit of intra-industry trade---it gives people more variety to enjoy.

Well, you know you can count on New York Times for idiotic protectionist argument. Man, it never disappoints me.
