A single land tax that pays its surplus out to the citizens is my vote for Capitalism 2.0:
Some libertarians advocate land value capture as a consistently
ethical and non-distortionary means to fund the essential operations
of government, the surplus rent being distributed as a type of
guaranteed basic income, traditionally called the citizen's dividend,
to compensate those members of society who by legal title have been
deprived of an equal share of the earth's spatial value and equal
access to natural opportunities. (See geolibertarianism)[1]
