That's not how it works. In the real world, some of the 10% would be slackers, and some of the 90% would think up ways to enable the slackers in return for some of their income. They, in turn, would need to employ more of the 90% to satisfy demand. Indeed, whole new classes of "goods" would be defined, such that only members of the 90% would be qualified to provide them. Of course, the 10% would strive to automate these away, only to find new classes arising of slackers with new demands to be satisfied by new entrepreneurs among the 90%. As a particularly lazy member of the 10%, that has been my experience. Long may it continue!
