You can steal from your children and your grandchildren with impunity because, after all, “In the long run, we’re all dead“.
“We repudiated entirely customary morals, conventions and traditional wisdom. We were, that is to say, in the strict sense of the term, immoralists. The consequences of being found out had, of course, to be considered for what they were worth. But we recognised no moral obligation on us, or inner sanction, to conform or to obey. Before heaven we claimed to be our own judge in our own case” – John Maynard Keynes
