“Keynes said, in his book, when he was answering criticisms that in the long run, his theories won’t work, and one of his very famous statements was, “Well, who cares? Because in the long run, we’re all dead.”
Well, the problem is, of course, that right now Keynes is dead and we’re still alive. In other words, we’re living in the Keynesian long run and we’re suffering from it.” – Murray Rothbard
