I feel that "billion dollar companies wanting to milk as much labor from poor countries as they can" is one of the only forces in the world that will actually take the time to go out and look for African Einsteins instead of just giving the jobs to their friends and neighbors.

It doesn't follow that because I said you can find people without important work in low-GDP countries, that there is no important work there. If you've ever been in one though, there are always people whose job seems to be "watching a single goat" and would be much better off training AIs to identify cats.
