“Would a Government Bureaucrat calculate a theoretical rent value and charge the owner that?”
Matt Bruenig

Why would I think of it like that? The Government is our servant, not our master , and has no right to “Own all the land”. Any Government which does as you suggest will end up in the scrap-heap of history, leaving chaos in its wake. What killed the Soviet Union was the ever-clearer evidence that the working class under Capitalism were infinitely better off than the working class under Socialism.
