I went to an Economic Society presentation last night about the role of statistical measurement in creating economic reality given by one of the stellar scholars of our time. That was the first slide of the night. This is the text below the picture:

Che Guevara, as Minister for Economy in Cuba, used American accounting systems (left behind by fleeing American corporations) to deliver, and increase, output in a socialist economy after the revolution.

You would think the presenter would be embarrassed to say any such thing, or if one cared to give the benefit of the doubt, is perhaps oblivious to the offence that might be caused or has no idea how this might be judged given how badly the Cuban economy has been managed. None of it. Understood it all and dared anyone to say a word. No one, of course, did.
