> At the heart of that problem is housing unaffordability. High housing prices do nothing more than steal from the next generation and bring us closer to having a divide between landed and unlanded people.

I'd completely agree here. It's difficult to blame democratic governments for this though -- throughout the west nobody wants to build enough supply to deal with the problem.

Your second part of landed vs unlanded. Implement a land value tax and distribute it as a universal basic income, and that solves that problem. Nobody wants that either, they think they like it and then come out "oh of course $favoured_group shouldn't pay it"

You won't see a land value tax for the same reason there are constraints on housing supply: because existing homeowners are essentially single-issue voters when it comes to do with anything about housing. Aesthetically progressive people turn into raging fascists the second you propose building slightly higher density housing near a train station that they're nowhere near.

In my ideal world I would:

1. Massively hike property taxes on non-income generating housing;

2. Make anyone owning housing subject to state, local and federal taxes on their worldwide income;

3. Get rid of preferential property tax rates and caps on property tax increases (eg Prop 13 in California). If you want to not force old people to sell immediately, defer their property taxes until death. This is exactly what Texas does;

4. Build for transit; and

5. Have the government be a massive supplier of social housing.
