Already largely done, and will take a generation or three to rebuild, if it ever happens.
But wealth accumulation means that on the auction for housing you are competing with someone who has 1000x more resources than you.
We can’t accept every single person who would rather live in the US or UK than El Salvador or Lesotho, unless we want our country to be like those countries, and according to the people who constantly try to come here, those countries are much worse than ours.

None of this has anything to do with disliking immigrants themselves. I know people of many different races and national origins and I like and respect them all. But just as I don’t think France deserves to have 10,000,000 Americans show up, not learn any French, and just import American culture and customs, I also think immigrants here should be expected to assimilate. That basically worked well for hundreds of years.
Pro tip: we are a culture of mutts. We draw strength from constant change. That's why we've been successful. And it's been dragging the right wing kicking and screaming the whole time. The things your great grandfather cried outrage about are now your treasured culture that must be protected.

The US was built by immigrants. Before our slow slide toward christofascism it was on our money. Out of many, one.

The most bold, the most focused, the most daring have always come to America with a dream of making it big.
We destroy that at our own peril. Break that down far enough and we'll become a culturally inbred irrelevant backwater. If you want to become the UK, that's how you do it.
