A class had insisted that socialism worked,
The professor then said, “OK, we will have an experiment. All grades will be averaged and everyone will receive the same grade.” (substituting grades for dollars).
After the first test, the grades were averaged and everyone got B. The second test average was 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 surprise, ALL FAILED and 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.
