This should piss off some liberal readers. Robin Hanson calls the above video an example of "natural hypocrisy":
Most people believe that redistributing money within a nation is good, but that redistributing GPA within a school is bad, and if asked why these should be treated differently, have little to say. My point isn’t to say one can’t come up with reasons to treat these differently. One could, for example, argue that we prefer differing school signals to help employers sort people into jobs, to achieve higher productivity so that the pie is bigger when we redistribute money. My point is that most people can’t think of such reasons, making it pretty unlikely that such reasons are the cause of their opinions.
