"....no payment, resulted in a reduction in blood flow to the "reward region". But the area "lit up" when volunteers earned money, and interestingly showed far more activity if a player received more than his partner."

Oh boy - I predict a rash of conservatives/economic neo-liberals (i.e., radical nutcase Chicago School capitalists) misusing this study, mistaking an apparently factual report for a normative one. ("It *is* such, so it *should* be such.") "See?! We *should* pay CEOs 300 million! And always give them more than the next guy! They'll be more motivated!"

Not to mention the male/female pay divide: "Men will lose their will to live if women make as much as they do! It's simple biology! Ya can't deny nature!"
