I think because we feel that there is no real purpose to being alive, we need entertainment and distractions.
I often wish we had a star trek society where people would work on things that benefitted society in some way, instead of for money. It would have much more meaning because your talents would benefit other people, not corporations.
Someone who likes to draw would just draw and become appriciated for having great art, much like open source works today. Or if you enjoy making beautiful furniture, or robots.
What is destroying us is that we all work for being rewarded by money, not for appriciation from our peers. For me personally, the appriciation i get for working on open source projects is enough to keep me going and being happy with the work.
Some people say that most people would do nothing if they didn't have to work. I think they would want to do something. Because almost everyone would want to feel they have a purpose besides just existing. That is why we feel empty now at most jobs.
