And TFW program aside, the same principle goes for the housing market. It’s much easier to convince some europeans to pay 1500$ a month for a 3-rooms apartment because they are used to expensive housing. They will generally be less informed about our consumer protection laws and accept any lease, legal or not.
If you want to see it with a more humanitarian perspective, what’s the point of getting so many immigrants if we can’t house them properly or give them proper jobs? It’s not helping them and it’s not helping us that much.
