People who don't empathize with you aren't always misinformed. Sometimes there are fundamental moral incongruities.
There are apt analogies of "the system is fucked and I'm just working in it" throughout US history.
Edit: for example, if you’ve rented or bought, you’ve contributed to the demand that makes the market price go up. If you were a landlord, at least you’d be helping provide supply that keeps the price in check :)
Distinguishing between rental markets and less pathological applications of market mechanisms is not exactly novel economic doctrine. And in fact, you'll have a hard time finding a tradition of economics without its own giant calling out landlords.
Landlords don't provide supply. Homebuilders do. It's pretty rare that those are one in the same in a market like SF.
I'm not saying landlords don't fulfill a valuable part in the housing puzzle, but saying landlords "supply" housing is absurd.
