66% in 2022 are paid? No mortgage? How does that compare to 1900?

No progress since 1980, unfortunately. Just oscillated a few points up and down from 65% https://www.census.gov/econ/currentdata/dbsearch?programCode...

It's not an "unfortunately", the U.S. population has increased 50% since 1980, using US census markers ~226m in 1980 to ~331m in 2020. It's an amazing benchmark to be at the same ownership rate despite growing this much in such a short time frame.

Further, ownership going beyond certain numbers does not necessarily mean good either.

Is asking questions to nobody in particular that you can easily answer yourself your idea of an argument?

Not in the US. I live here: https://www.bundesbank.de/en/publications/research/research-...

Keep in mind that the mentioned "social housing factor" does exist, but it is also almost entirely in the hands of Gen X and older because building social housing had already stalled by that time.
