B…but…the Internet was supposed to remove the importance of place.
DC has gone up in price in the last 15 years, but NYC and SF have been expensive since at least the 90s. I recall my sister wanting to move to SF after college and complaining about it being more expensive than New York.
And NY was never cheap. My father said he paid $500/mo for a 2-bedroom near Columbia University around 1970. Not the safest area at the time — local yoots would sit on their steps with baseball bats and watch for people from further uptown, so to speak. That’s probably equivalent to about $2500/mo right now.
