There is no Tycoon Party in the United States to impose ideological uniformity on a group of billionaires who, by their very nature as übermensch, march to their own drummers and differ on many matters. Some are philanthropically minded, others parsimonious; some are pietistic, others indifferent. Wall Street hedge-fund creators may donate to Obama and be card-carrying social liberals on matters of love and marriage, while heartland types like the Koch brothers obviously take another tack politically. But all of them subscribe to one thing: a belief in their own omniscience and irresistible will.
