As someone else noted, you left out Fascism. Mussolini is famously reputed to have said, “Fascism should more appropriately be called Corporatism because it is a merger of state and corporate power”
To me it is a significant omission, because I believe that is exactly the description of the totalitarian system we are living under today.
That doesn’t sound a lot different that Socialism or Communism. At some point the corporations and government merge and we have totalitarianism or statism.
The funding of GM, GE, Solyndra and other boondoggles against tax payer approval is thuggish. It crushes smaller companies and chooses winner and losers while not letting smaller but possibly better companies and products win.
