Housing prices, of course.

It turns out that refusing to build housing to meet demand has serious consequences: homelessness, street crime and filth due to homelessness, inability to hire for any but the highest paid jobs, families leaving because you can’t raise kids, and being passed over for other areas by new talent among others.

I saw a national map recently of places likely to lose congressional representation over the next 5-10 years vs places that will gain. It was almost perfectly a map of places where you can’t build housing vs places where you can.
