For centuries Kings and Despots tried to control trade. Then the United States came along and it favored trade. Trade expanded and prosperity followed. Nations now try to restrict migration. Some try to restrict emigration (North Korea and Russia for example)and some try to restrict immigration (The USA, Australia and most of Europe). Restricting migration makes the world poorer than it could be both economically and intellectually. The analogy is not exact but in general the countries that welcome migrants will prosper.

I see a future world where people are allowed to move away from places without opportunity to places that offer them more. The result will be an amazing increase in prosperity throughout the world. It worked for trade in goods and it will work for migration of people.

Of course there will be difficulties and obstacles to overcome. But again using trade as an example slowly lowering the barriers to migration will mitigate much of the difficulty while reaping much of the bonus. Certainly the new system should not allow new immigrants to be an undue burden on the communities they join. But these real objections can be overcome to increase the well being of millions of people around the world.

I predict that countries that manage robust amounts of immigration will disproportionately prosper compared to countries that are restrictionist about immigration.
