So that solution is to sort humanity and get best specimens to live in one place and send all the undesirables to somewhere already supposedly worse off?

I think if we go all the way into dystopian solutions, a fair one would be to run a lottery for every baby and send them to a random family in a random part of the world.

Wait...

(that's an honest "wait...", I set out to write a fair but very dystopian example and got to where we are now :))
