Merit was the keyword here. Merit can get you more or less so it is valid qualifier. If you want more, you need to merit more. If you don't want more, merit less. IQ is not necessarily a more or less qualifier as production might be more meritorious. It'd be tough on people like GWSuffForBrains who'd be cleaning a toilet one day every four months when he wasn't on vacation. Maybe he could be taught to lick his balls (golf balls?).
