how to make a perfect world or save the world: replace all taxation with ground rents.
Taxation destroys wealth,
but ground rent creates wealth

Taxation adds an extra cost to work. So marginal work (work that is only barely profitable) becomes unprofitable. So less work is done.

Progressive tax does not change this: less tax in one place means more tax in another. For every penny the government takes in tax, less work is done.

Ground rent has the opposite effect: land is used more efficiently (to pay the rent), creating more wealth. Even if ground rent costs the same as tax, additional work can then be done tax free.

Ground rent improves the economy in many other ways as well. And a healthier economy grows faster every year. Compound growth means the effect is enormous.
