> we need to be careful with the fine print of such policies as to not destroy our own economy.

Au contraire. Many Americans and Europeans would get a huge and valuable smack with the clue-bat if there were no immigration restrictions, and if licensing schemes designed to create arbitrary shortages of e.g. doctors were eliminated.

I think immigration policy will eventually be nonexistent, but before then many things need to happen. The developing nations need to achieve a certain quality of living across the board so that the people there don't all just decide to get up, and leave.

Economies need to become less decentralized, and more global in their scope. Which arguable is very much a reality today, but I think this is simply the beginning.

And there's a whole host of other developments that need to happen, but I believe eventually will happen in the coming decades. We'll see a more homogenous world, yet also a more diverse one.
