The author’s argument is that creating more supply will further increase housing prices because more educated professionals will move into the city. I see two issues with this argument. One, I don’t think it’s the limit of affordable housing that’s preventing educated professionals from moving here. They’re already coming here in droves, which is the initial cause of this problem (according to the author). Who says adding more housing will further increase the influx of these people? Two, suppose the above hypothesis is correct, then wouldn’t their salaries go down? This is the entire basis of the author’s argument as to why housing prices keep climbing; because by moving to the city, these professionals are immediately increasing future earning, which they borrow against from their well-to-do families. So doesn’t increasing the flow counteract the forces driving prices up by decreasing these future earning?
