I totally agree, it's all about increasing supply: build more housing. Getting rid of zoning laws and increasing building heights, etc, are a great start.

But, to do that, we also need to work with developers to help reduce the underlying cost of housing. It's not just the cost of land, but also the actual cost of building it too. Once the actual cost of housing goes down, they'll be able to build much much more and they'll be able to profit even when the price decreases significantly which keeps them building more and more, as long as there's enough competition.
