Did we really need a study to tell us that intelligence has nothing to do with wealth? Haven't the last seven years been enough to prove that? You can get rich if you're smart, lucky, and work hard to earn your wealth. Maybe. On the other hand, you can be as dumb as dirt and end up as rich as Croesus if you're lucky enough to be born into a wealthy family. If you can manage that, you can fuck up ever job you get and still become president. And you can fuck that up too, and still be rich.
