It <i>appears</i> World War 2 came from fascism… which came from fed up people… because massive unemployment… because failure to handle productivity increases.<p>Productivity increases by itself will never cause problem.  If we become 1000 times more productive overnight, we have <i>loads</i> of excellent solutions to handle it.  Like have people work only 1 day per year, relying on voluntary service, increase material wealth like crazy…<p>But we&#x27;ve gotta admit, our society sucks at absorbing productivity increases.  Just watch what will happen to professional drivers in the 10, 15 years to come.  If we don&#x27;t come up with something, the shock will be brutal.
