I saw this tweet recently, by patio11: https://twitter.com/patio11/status/1199366332468224000 "Tokyo has positive population growth of about 100,000 people a year, and rents and home prices are roughly stable for last decade. How? Outconstructing NYC. And LA. And SF. And Boston. And Houston. Combined. Every year."
Tokyo is an 845 mi² megacity. Is population growth of 100k/yr something a city should aspire to? At a certain point I feel like some kind of family planning makes sense at larger levels of society just like it does with the family unit. I don't look forward to the day when there are 1000 mi² of concrete and 20M people crammed together where San Diego used to be
Those are the options. You can decide which one you look forward to more.
