Quote of the day: Pessimism, a poor predictor...

Here I once again borrow Don Boudreaux's Quotation of the Day.

From the gifted economist and author Deirdre McCloskey, in her book Bourgeois Equality:

Pessimism on the basis of the most alarming of today's trends is jolly good fun, I know. But since 1800 it has been a poor predictor.
