An economics professor 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 for all, for society. The professor then said ok, we will have an experiment in this class on socialism.
He said that 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 was given 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 hadn't studied much for the first test had studied even less, and the ones who studied hard weren't motivated to study hard again, and they 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 .... and the professor told them that the socialism they wanted would ultimately fail, as they had, because the reward of success normally goes to those that work harder, but when government takes the reward away; few will try so no one will succeed.
