I live in Canada. While it is not the fault of individual immigrants, even the Government of Canada and big banks have admitted that abuse of the International Student and TFW programs has put a lot of strain of public infrastructure and housing supply and has suppressed wages. These issues have absolutely objectively affected the average Canadian.
Every now and then you get someone on social media try to be smart and smugly say something like, "International Students can't afford to buy a house. Explain to me how they're driving up the cost of housing." But they fail to realise it increases demand for rentals, and people buy single family homes to rent the rooms to those students, and so the demand for those rentals drives up the cost of houses.
You can acknowledge that not all immigration is good without blaming individual immigrants themselves. I'm always shocked when people who understand infinite growth is a fallacy when it comes to the corporate world, don't understand that trying to grow the population into infinity year after year is just the government equivalent of that fallacy.
I love the thing they do in TOS where they meet some omnipotent character that can transform matter and they determine there has to be some power source the character is using.
