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 Socialism".
All grades will be averaged and everyone will receive the same grade so no one will fail and no one will receive an "A"...
After the first test, the grades were averaged and everyone got a "B".
The students who had studied diligently were upset and the students who studied less were happy.
As the second test came around, the students who hadn't bothered to study - studied even less!
The ones who previously had studied so hard decided they wanted a free ride. So they too, studied less.
The second test average was a "D"! No one was happy.
When the 3rd test rolled around, the new average was an "F".
As the tests proceeded, 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.
When the final results were released, to their great surprise, the students all failed.
The professor told them that socialism would 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.
Human nature will always cause socialism's style of government to fail because the world is made up of producers and non-producers (makers and takers).
