At present, governments and corporations can take risks and others will pay (the problem of externalities).
They can ignore problems, pollute, destroy resources and gamble away the future. They know that the tax payer will bail out the government, and then the government will bail out big business.
Ground rent changes that. There is no tax to bail them out. And if they harm the economy then land values go down, so ground rents go down, and they go out of business.
But what happens in a genuine crisis, like a war that is not the government's fault? Simple. A government that can deliver safety in such a crisis can charge premium rates.
It all hinges on your credibility. With ground rent,
anybody who provides real evidence of good
government will thrive.
