Well, I want more multifamily housing (apartments or condos) to lower prices in good cities near pubic transit.
So let me propose: a wealth tax on land! ("Georgism"). But not a tax on the "value of improvements," i.e, buildings. This disincentivizes single-family homes near train stations (widespread in the town I grew up in) and is very low-cost to collect.
I don't know where you're writing from. But here in California, the source of all evil (Prop 13) originated with single-family homeowners trying to *escape the property taxes that result from their opposing new development.
Given how spectacularly CA housing policy has failed, perhaps it's time to try the opposite: Let's abolish all income taxes and exclusively tax land instead! (Land taxes have the property of being extremely progressive wealth taxes that are dead simple to administer.)
Now my corporation owns my house, I rent from myself and since the rent my corp is charging is so incredibly low its essentially a write off.
