>This is exacerbated by an aging population and restrictive immigration policies.

Sans the covid anomaly, immigration has never been higher in Western nations. The issue isn't restrictive migration. It's that we're not treating nurses well. That means fewer people pick this career, and more nurses leave prematurely. Suggesting that we need to import more nurses is only admitting that migrant nurses are willing to work for worse pay and worse working conditions, and I don't think that's fair to anyone.
