Someone comes in with a gripe that the bottom quintile imposes negative externalities on their education system. Your response is that the same people impose positive externalities when they grow up. These are not the same. If they were still imposing negative externalities when they grow up, I wouldn't want them to exist around me, and sending "non-average" people to space or some similar dystopian project [or jail] would be the correct game-theoretical response.
