Canada

I'm not advocating for a system with infinite growth. I don't disagree with your first point, there's nothing inherently wrong with a country having a stagnant or declining population, but that's an over simplification. You need to look at the demographics. When more people are retired and drawing on services than there are people to work and pay for those services, that isn't sustainable. If you need more care homes for the elderly, than you need more people that work at care homes, for example.

If the housing prices are what they are now, with the current supply and demand, how would stopping new immigration cause a crash in housing prices? The aricle we're commenting under says that 1/5 of construction workers are immigrants. Would you want to stop bringing in more construction workers to build housing given the current crisis? Like I said before, immigration policy is complicated and needs to be nuanced and strategic, it isn't an all or nothing situation.
