Earlier quoted context omitted.
Land price will adjust accordingly in response to any positive economic news. If you want an unalloy good to come out of these programs, tax lands. Otherwise, any welfare program will just get some of its value captured by landlords.
Land value tax won't help unless you greatly reduce the zoning and regulation over what can be built on the land. Putting the land to its most efficient use isn't possible if all you're allowed to build is a two-story detached single family house.
The issue is we zone something and it stays that way until it's manually reviewed and rezoned. The district has no ability to change itself according to the circumstances. It has to rely on a third party that acts without due haste and with great reluctance.
