<p><pre><code>  Optimists argue that throughout the history of capitalism, new technologies 
  have always led to new jobs in the long run. But pessimists say that this 
  trend isn’t guaranteed to continue, and the chance that we are in an era 
  where wealth is created without jobs raises very thorny questions about how 
  that wealth will be distributed fairly.

Nothing keeps the populace employed as good ol&#x27; agriculture does!<p>Sure there are &quot;new jobs&quot; but job creation doesn&#x27;t have a fundamental law analogous to the law of conservation of momentum.  Efficient tech is at it&#x27;s very heart a job destroyer. So with growing population and shrinking meaningful jobs what we end up with is civil unrest. Hence we have people employed doing busy works who come home to constant stream of &quot;news&quot; and &quot;entertainment&quot; and another section doing the busy work churning out these contents! Apart from breeding inequality it also breed discontent. Perhaps evolutionarily humans are wired to feel satisfaction at the end of a hard days work.
