Landowners (and retired homeowners) will make more money under ground rent, even after paying their rent. (Details.)

Home owners will pay less even without compensation, because the amount of land they own is trivial. (Details.)

Renters will pay less because building new apartments (with almost no ground rent) will become so cheap. (Details.)

People who don't own much land will of course make more money. Because the economy will grow more quickly, and they won't pay any income tax.

The sick and disabled already create all the money they need simply by existing, though at present they don't get to see that money. (Details.) Ground rent simply measures and returns that money.
