No, it's not. The people who own houses pass them down to their kids. As people invading a neighborhood, YIMBYs may be new, but they are not that young. They are early middle-aged and wealthy. They are trying to move into elite neighborhoods and cities that they can't afford, not trying to avoid homelessness. That's not a crisis. All of them can afford property, just not the best property in the world, (not coincidentally) near the jobs that pay them the most.
The problem is normal-case housing affordability, not elites wanting to build high-rises. Normal housing affordability is ruined due to the asymmetry between resident homeowners as buyers and wealthy buyers. Wealthy buyers are trying to extract wealth from housing. Resident homeowners and renters are the extractees.
The YIMBY goal is to make somebody in e.g. SF refusing to sell, and/or refusing to allow the houses on the corner to be demolished and a high-rise put in, the enemy. I have no idea why YIMBYs think they are either more rational, more likeable, or more victimized than that homeowner. Maybe all of the self-praise.
