... why don't they? Europe goes from skyscrapers to block of flats to apartments in the suburbs and very few houses on the very outskirts. The US seems to go skyscraper - single family house
Because the entire US has a "missing middle" and a suburb problem brought on by big corporations. You get into you car, burn gas for 20 minutes to go to their 1 super mega everything mall. They also banned the idea of having local store in a "residential area" to force you to go to the everything store.
Not sure where you got "appartments wouldn't work there".
The entire video is about the missing middle, the midrises /appartments missing between the suburbs and the city. As pointed out in the video, the missing middle comes from the fact it's illegal to build midrises in most "residential areas"
