San Francisco and Manhattan (as well as most of Western Brooklyn) are almost exclusively for those who the media would call “elites”. This wasn’t always so. Go back to the 90s, 80s, 70s, and 60s and the population of these areas is much more diverse. You’d think prices can’t possible go higher, but income inequality is actually increasing—so they can. In 10 years there will probably be zero market rate properties in either San Francisco or Manhattan under $1 million. It’s already a rarity, but soon it will actually be non-existent. And unless things change in another decade that bar will be $1.5 million, and so on.
