There was an article on HN front page a few months ago which stated(paraphrased) "building more housing to reduce prices is a right wing ideology that doesn't match reality" or some such. I'll reply here if I find it.

hn.algolia.com is a great search interface. I searched “housing” and top posts in the past year and didn’t see anything related to your quote on the first two pages. Maybe I need to search deeper.
