And immigration fixes that housing pressure how? This is no different than queues and backpressure. If housing is too expensive for tens of millions of workers, and supply lags, why would you increase housing demand? You must destroy demand until supply catches up.

Most of America doesn't have this housing pressure issue actually, only the top cities. And I believe you have the causation backwards; it's not "immigration would be bad because housing is rare" but rather "housing is expensive in California partly to keep immigrants out".

Some people say the immigrants will help because they'll contribute to construction. I think this is true but not an important point, and besides it probably annoys the construction unions to say it. Rather, immigrants can move to parts of the US that are cheap and starting to experience disinvestment, which is still most of it.

Besides that, housing isn't per-person, so if immigrants are more willing to live in families or have roommates it's less pressure than a lot of singles. And they pay taxes which you can use to build the housing.
