Paul Krugman is at it again, bemoaning the mendacity of politicians who, for “careerist reasons”, will never admit their mistakes and therefore lock themselves into bad policies. He even quotes Ralph Waldo Emerson:
A foolish consistency is the hobgoblin of little minds,
adored by little statesmen and philosophers and divines.
And Krugman’s solution to this problem? More power for the politicians, of course.
