I don’t think the people building skyscrapers in the middle east and the people hoping for h1b in a tech company are the same sort of people at all in this case. Consider also how China has been making literal inroads into Africa the past few decades. There is a pool of low skilled labor that wouldn’t mind a little higher pay and a lot more stability and security to go along with that. There are still warlords destabilizing nations in this part of the world. Plenty want out.
