Here’s the problem - some people will still make the choice to have ‘get ahead’ by having both partners work. They will then use their relatively greater economic power to get better housing and more stuff. So others will join them, and they will bid up housing (because it’s the most important thing) until we’re back to where we started and even those who don’t want to do that now have to.

It’s a sorta tragedy of the commons situation.

The only real solution there is for governments to look at social housing, and also to try to produce A glut of house building.

Because until we have one or the other (or both) people will just keep bidding up accomodation to the edge of what’s affordable on two incomes.

Yes, there will likely be that phenomenon, but will it occur faster than the approx 2% level of optimum inflation?

Creating a universally-available baseline lodging situation for everyone is certainly a public good that would yield a LOT of benefits from eliminating homelessness (benefiting not only the homeless but also everyone who their problems affect) to promoting family stability.

Whether the best way is to incentivize a glut, subsidize social housing, or just provide a housing stipend for anyone in need, another system, or some combination of all-of-the-above should be subject to study and experimentation.
