Public schooling is horrid anyway. You're not educated, you're molded and conditioned. Home schooling (in its many variations) is phenomenally better.
Practicing up for Guitar Hero is pretty pointless however. Even the best "cyber-athletes" barely make enough to really live off of, and that requires dozens of high profile tournaments every year, alongside endorsements and such. Those are also generally more skill based games, like Quake and StarCraft. On the other hand, Guitar Hero is little more than memorization.
Ian, what exactly would be a living that benefits society? As far as I can see, the large majority of people aren't in those occupations as is. Most merely work to make their lazy overlords richer, whether it be a manager, CEO, or their government. Following questionable rules and living by the established status quo isn't much of a life at all.
