Soccer crowds in England like to abuse match referees by chanting: "You don't know what you're doing." If protesters had been able to get near the World Economic Forum in Davos last week, they could justifiably have aimed the same chant at the world leaders who assembled in the Alps.

These people are meant to be the "masters of the universe": presidents, prime ministers, bankers, billionaires. If anybody can make sense of world events, it should be them. But the air of confusion in Davos was both palpable and alarming.
