In other words arguing Keynes vs. Marx and whatnot is a waste of time. The powerful always manage to skim off value for themselves and when the system collapses they laugh all the way to the bank while the rest of us argue about whether or not it was real communism or real Keynesian policy.
True. But Keynes is tought at every high school in the Western World and parotted in the news each and every time as the best thing to do, so say clever minds. Propaganda, nothing more.
