Only an economist can consider a theory like that for more than a few seconds and not laugh hysterically. As Tom Woods has said, following this logic, the best thing we could do for our economy is build a huge armada of amazing battle ships, have Japan do likewise, then float them to the middle of the pacific and, after evacuating them (surely, the loss of human life is not a necessary component in this economic model, is it?) blow them all up.

Rinse, wash, repeat. We're all rich!
