Back in the cave days, everything was done collectively. Human survival depended on each other, so they had to huddle together to survive dangerous animals. There was no individualism. Everything must be done for the greater good. For everyone’s survival. Everyone was expected to be selfless. Fast forward now… where we no longer must huddle together to survive dangerous animals, selflessness that has been long glorified as a virtue, may be one of the roots of human misery.
