Add in that wonderful quote from Old Andrew, "If you want to learn how to cooperate effectively with others, then the last place you’d start is in a group of teenagers being made to do school work. This is like saying the best way to learn how to make pork sausages is by being imprisoned in a pig farm with a half-dozen rabbis. Putting together people who are neither experienced at doing something, or particularly inclined to want to do it, is not how you learn to do that something."
From Theo Spark:
An Experiment in Socialism
An economics professor at Texas Tech said he had never failed a single student before but had, once, failed an entire class. The class had insisted that socialism worked and that no one would be poor and no one would be rich, a great equalizer. The professor then said, "OK, we will have an experiment in this class on socialism."
All grades would be averaged and everyone would receive the same grade so no one would fail and no one would receive an A. After the first test the grades were averaged and everyone got a B. The students who studied hard were upset and the students who studied little were happy. But, as the second test rolled around, the students who studied little had studied even less and the ones who studied hard decided that since they could not make an A, they studied less. The second Test average was a D! No one was happy. When the 3rd test rolled around the average was an F.
The scores never increased as bickering, blame, name calling all resulted in hard feelings and no one would study for anyone else. All failed to their great surprise and the professor told them that socialism would ultimately fail because the harder people try to succeed the greater their reward but when a government takes all the reward away; no one will try or succeed.
I'm not sure that it's all so cut and dried but the historical and cultural data is pretty strong.
