A world of free movement would be $78T richer
I&#x27;m not entirely sold on the idea of cramming the vast majority of the world&#x27;s population into the subset of countries that are relatively wealthy and well-run. In practice, the cramming continues within those countries into the most favoured cities.<p>If we are thinking of pie-in-the-sky ideas like open borders, then why also try to think of a way to spread good government and wealth across all parts of the world?
 I.e., spread the best practices so they become universal.<p>Some ideas in the past, like Europe colonising and controlling much of the world, are obviously out of fashion today. Yet ironically many people have voted with their feet (or would like to, if given the opportunity) and moved to Europe.
