I always ask why Muslims are moving to Muslim countries....Saudi Arabia has a lot of land and money to take care of their fellow Muslims.
Because the wealthy Arabs like the Saudis and the folks in the UAE don’t want the Muslim equivalent of riff-raff, mostly coming from North Africa and parts of the Mediterranean, living in their countries! That’s also why these countries never offer to take in Palestinians. They’ll use them to antagonize Israel, but keep them the hell away from their borders!
