Yea they're big no doubt. If we were starting from scratch I think we'd have lots of Portsmouth, New Hampshires and only a few New Yorks (you need that level of density for certain specializations - think quantum physics or neurosurgery). So imagine the US, but maybe 5 New York level dense cities, and the rest of the country like Portsmouth. Unfortunately though, I think we can't really undo the damage that's been done so far, so the best we can do is try to heal these cities and make them dense in a nice way. Hong Kong is an anti-pattern, and so is Houston. IMO.
