I think creating a permanent world peace would be easier than convincing progressives to give up their tired, inaccurate housing market tropes.
It is impossible to have a constructive conversation with people who refuse to accept basic facts, and I don't think they have any idea how counterproductive it is.
If people stopped accepting the claim of 'progressive' from anti-housing anti-poor people just because they self-label that way, that would be a good start.
