An economics professor at Texas Tech said he had failed very few students but had, once, 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 socialism."
"All grades will be averaged and everyone would receive the same grade meaning, obviously, no one will receive an A." They all agreed to this. After the first test the grades were averaged and everyone got a C. 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 and name calling all resulted in hard feelings and no one would study for the benefit of anyone else. To their great dismay the professor failed them all. Then he sent all of them this note: "A socialistic government will also ultimately fail - because when the reward is great, the effort to succeed is great, but when government takes all the reward away, no one will try or want to succeed."
