You don't really seem to understand economics. Ask anybody (or yourself) if they would prefer a world with no video games, movies, sports, music, or any kind of commercialized entertainment. The answer is no. Everybody wants that stuff, including you, and with that resounding demand comes industry and money making. The people of the entertainment industry have done just as much for society as any other working class citizen.
Thank God for these "self-obsessed" people and their "selfish" life ambitions. Shithead.
