If I take something from you and decide what you will receive in return, then you have lost authority over your labors that produced it. You have lost your freedom to decide. You are then a slave as it is the master who controls your labors.
Communists believe that the loss of control does not mean a loss, but a win, if the government returns something to you. If that is the case, then we should all gladly fork over 100% of our earning for the great investment that the communists believe the government provides. Right?
I am not a communist. I believe that I, and I alone, can decide what is best for my labors. I decide how to provide for my family and my community.
