Peter Drucker seems to never go out of style. In 1974 he said that company managers should take the Hippocratic oath. Do no harm. Presto. None of this Wall Street crap. No embezzlement. No violation of the fiduciary duty. No theft. No bribery. No extortion. No massive environmental problems. No abuse of workers.
As my kids are fon of saying, this is a random thought.
