canada got to the point that they can't turn off the immigration faucet, they need it for their economy to survive, but people have come to hate it so much that they can't maintain it, they're in for a collapse because of it
By scaling back and "living like college students" (living like families in most of the world except the US & Canada), they're going to be the only groups of people who have any buying power to buy new homes when they finally get constructed. Meanwhile y'all will continue bitching and moaning about how fucked you are while the immigrant generation laughs their way to comfortable retirement and a better future for their children in your country.
