An economics professor at a local college made a statement that he had never failed a single student before, but had recently failed an entire class. That 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 this plan". All grades will be averaged and everyone will receive the same grade so no one will fail and no one will receive an A.... (substituting grades for dollars - something closer to home and more readily understood by all).
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. 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.
