An economic analogy from Texas Tech
An economics professor atTech 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 they wanted a free ride too; so they studied little. 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 trying harder to succeed for the greater the reward works, but when a government takes all the reward away, no one will try or succeed, and everyone fails.
(I wonder if academia would today allow experimentation like this and award the class average.)
