One of the most overused words in public life is “hope”, up there with “change”. Yet it matters enormously. Politicians pay close attention to right-track/wrong-track indicators. Confidence determines whether consumers spend, and so whether companies invest. The “power of positive thinking”, as Norman Vincent Peale pointed out, is enormous. … Now hope is on the move. According to the Pew Research Centre, some 87% of Chinese, 50% of Brazilians and 45% of Indians think their country is going in the right direction, whereas 31% of Britons, 30% of Americans and 26% of the French do.
