When someone complained that Keynes's recommendations would lead to inflation in the long run, he famously replied, "In the long run, we are all dead."
He was right about that. By the time the chickens have finished coming home to roost, Keynes will have been dead quite a long time.
Behind Keynes's attitude as revealed in this comment is, as I once read in "Culture Wars," the fact that he was a homosexual. As such, he was chiefly interested in power and pleasure in his own lifetime, and had small concern for the future. He had no family, no children, and no particular interest in what might happen to other people's children when they grew up--or their children's children.
