to ground rent
Changing is simple. Every year remove more taxes and increase the single rent to be slightly less than you removed.
But how to persuade governments?
If they are capitalist, point out that ground rent creates far more money.
If they are socialist, point out that this will create the ideal socialist society. Ground rent works better than top-down socialism, because power corrupts. So top-down socialism inevitably becomes capitalist anyway.
If they care strongly about anything, point out that they can create their ideal government.
If they don't listen, talk to others. Big ideas need a long time to settle in. You just need to get the idea on the agenda.
And if they never listen, don't worry: ground rent is inevitable so will happen anyway, sooner or later.
