The housing crisis isn't just supply side. When you allow millions if immigrants into a country (legally or otherwise) they need a place to live.

If you are interested in the country maintaining the status quo in terms of retirement benefits and quality of living, immigration is necessary.

Who's quality of living? If no one can afford housing, QoL is poor. I guess it improves billionaire quality of living though.

...that's why we need more housing?

Built by more immigrants? That is turtles all the way down.
