Imho, housing technology is stuck in the last decade. There is no reasonable government that is trying to fix the problem (housing requires transportation and common infrastructure). Hong Kong is an example of how to let everyone live together.

The west could leverage by doing that plus having an option to have a country side home and car for the weekend. Instead we have busy highways, old buildings, slow common transportation, etc...

New York is a good example but it blows my mind why they don't invest more in the subway, modernize the buildings, etc... Plus it cost a fortune to live there.
