Three weeks ago, Stein Ringem, Professor of Sociology at Oxford University, wrote a rather smug op-ed piece in the Financial Times entitled “Time for economists to eat humble pie . . . again,” ridiculing all the economists who had been criticizing Mrs. Merkel for not being more forthcoming in negotiating debt relief for Greece and other over-indebted European countries, who had warned that the euro would collapse if Mrs. Merkel did not relent in her opposition to bailouts, proving her economist critics wrong. Rejoicing in Mrs. Merkel’s vindication, Professor Ringen let loose on her critics.
