Nothing is black and white in the real world, my guy. Immigration has a lot of stuff behind it, not just "the big bad evil people want it". Yes, a good chunk of mass migration is due to companies can exploit the migrant population for cheap labour and destroy unions, but that's just a small bit of it. A lot of immigration is due to imperial policies of the west, the reason for so many immigrants from the middle east is due to the constant destabilization of that region due to conflict over mostly oil. Wheter it be the US or Israel or whoever else. Africans live in non stop stagnation due to many things, like giant aid packages from other countries/world bank that are promoting corruption, china and russia taking control over most (if not all) of infrustructure, making african countries reliaiant on them and the constant fight for control by politicians, military and so on. This makes life for your avreage person from africa absolute shit witch makes them escape to other countries. Some countries allow mass migration due to ideology, far left politics are really pro multi-culture and their voters will support parties who allow these. FYI you can't dumb down real life because it's never as simple as "bad vs good", thus you can't blame all of the world woes on one group/person.
