I am a fan of both men. I have learned a great deal from paying attention to their utterances, even as they largely go in such opposite directions. Everybody interested in economics should read Mr. Greenspan's book, and everybody likewise should keep up with Mr. Ritholtz's financial blog.
But did I see the last few days coming, in which the two become less ideologically distinguishable? Nope. And that's to Mr. Greenspan's credit.
