Liberal governments will do everything but the one thing that will solve the problem: make it much, much easier to actually build more housing. Everything else is just pointless busywork.
This is not really guaranteed to solve the problem. It will only be a part of the solution. In many countries, including Europe, new properties are quickly snatched by investment companies that have much easier access to capital than private individuals and can easily afford to pay above market prices. People shouldn’t really have to compete with companies or “investors” on the housing market.
People don't like to rent because of instability or unpredictability of pricing. But a large and growing long term rental market where it's straightforward to find a new place and nobody has an incentive to kick you out or raise your rent is really just fine.
You might be thinking, right but if you rent you'd be giving up the ability to make all that money from appreciation that homebuyers get BUT THAT IS ACTUALLY THE PROBLEM WITH THE ENTIRE SYSTEM because you can't have affordable housing and also have housing as a guaranteed investment that always builds wealth the two concepts are fundamentally incompatible with each other and when you get that you're really starting to understand the problem.
