Housing can actually be fairly affordable in Europe. Berlin until about 5 years ago had incredibly affordable housing for such a nice city…then it simply got more popular until that wasn’t the case anymore. Tokyo would have similar problems if its population wasn’t actually shrinking now (as are Nagoya and Osaka), since it’s a nice place to live, and housing isn’t very restricted beyond having to rebuild everything every 30 (SFH) to 50 (apartments) years.
San Francisco should look like Hong Kong or Tokyo. If you want a quaint small town move to a quaint small town. World cities are not small towns and trying to contain them to preserve their “character” just leads to affordability crises and homelessness among other problems.
If Detroit suddenly became a hot place to live and it wasn’t upzoned the same problems would start happening there.
My point is that, with few exceptions, housing is always expensive in places that are popular. If you want affordable housing, turn your city into Cleveland, don’t turn it into Hong Kong.
What if one of the most powerful politicians alive doesn't get to make this particular decision? She'll be so disenfranchised!
You mean to rent?
What about people who want to buy a home, have space, and have generational wealth?
You are unlikely to find that in Berlin or any major western city.
The only places to buy withing reach of the middle class are tens to hundreds of KMs out of these cities.
Berlin, and may I add Vienna, are anomalies. Vienna's population peaked in 1910. Berlin's population peaked in 1943. They were both capitals of an empire at their peak time. Then they became less important, and their population decreased. Now they have been in a very unique situation with their new population growth, because they already were designed for a larger population.
You can't generalize from Berlin and Vienna to other, more normal, cities.

It's been getting a bit more expensive due to Chinese students and also people moving north from England but it's still very affordable compared to most places.
