Human society was shaped by sharing! If we hadn't shared shelter, food, care for the young, companionship, etc. society as we know it would not exist today.
If you're old enough you should remember when the internet was just ramping up and everyone was talking up the new paradigm. We were once again part of a "global village" where people in every corner of the globe could share information, ideas, money, etc, etc. Offices would become paperless, communication would become instantaneous and life would look more like an episode of the Jetsons or Star Trek.
