Thomas F. Schaller on the U.S. Postal Service. Over the years, I've written my share (and probably some other folks' shares) of jokes about lethargic or insane postal employees. I've also done what everyone does, which is to blame the post office when I was tardy in mailing something to someone. The truth is I think the post office does a great job providing a vital service for fees that, since they can't raise 'em by fiat, pretty much guarantee they'll always be operating at a loss. In this blog post follow-up, Schaller adds another point to his argument.
