300k is living with a roommate level IMO unless you’re just looking to buy a 1 bedroom and not have kids.
This is extraordinary hyperbole that pretty much ignores what it’s really like in the Bay Area - many people making $100k or even less don’t even live with roommates here if they don’t want to. I make over $300k myself and the only reason I have a roommate is because she’s one of my best friends and I am helping her out while she’s early in her career.
There’s no need to put down another place just due to whatever biases, especially if there are few facts behind it. It’s ok to like where you’re at without going to extraordinary lengths to stretch it to everyone.
Absolutely agree that you can afford to live alone if you do not particularly care about buying.
