    stinction. Why were some people cleverer than others? Why did intellectual distinction run in some families? And how were intellectual abilities distributed in the population? Galton came to two conclusions. The first was that ability owed more to nature than to nurture. The second was that the range of mental powers between the cleverest and the dumbest was enormous? “reaching from one knows not what height, and descending to one can hardly say what depth? He put these together to produce a theory of human inequality the more open society becomes, the more an aristocracy of talent will replace an aristocracy of birth. Galton s argument contained a good deal of nonsense. He understated the importance of nurture, and he ignored class privileges. But it did offer an important insight that a free market in talent could end up widening social inequalities. The rich get richer America, the country with the world s freest market in talent, is seeing a dramatic increase in inequality. Emmanuel Saez of the University of California at Berkeley and Thomas Piketty of the Ecole Normale Supérieure in Paris have dissected tax records to examine change fuel dispenser s in income distribution, and found that the share of income going to the highe fuel dispenser st-earning 1% of Americans doubled bet fuel dispenser ween 1980 and 2004, to 16%. The share going to the top 0.1% more than tripled over the same period, to 7%. Part of the reason lies in social convention Europeans have strong cultural objections to paying their CEOs the sort of salaries that American bosses get. Part of it is political inequality has risen faster under the Republicans than under the Democrats. The unions are weaker than they were. But a bigger reason is rising returns to talent and skill. This is most obvious with sports stars and Hollywood celebrities. The picture is a bit murkier when it comes to CEOs. There are well-publicised examples of company bosses who pack their board with cronies and rig their compensation so that they profit whether their
