I propose a simple thought experiment: Lets move all the Pakistanis to Germany, and all the Germans to Pakistan, leaving absolutely nobody behind at either end 100% compliance. (Its a thought experiment: we can do this.) Come back in five years and measure the last year of old GNP with the now five years later GNP in both countries. What would you bet would be the outcome?
Pakistan will be making really great cars and motorcycles.
