The only way for a government to redistribute a person's wealth is to take it away by force and then make the decision about who is to receive it. It must regulate how much a shopkeeper can charge for his goods. All economic freedom is lost, and with it, the freedom of individual autonomy is lost as well. Socialists like to argue that under socialism, everything is fair and wonderful, and everyone is free and happy, because everyone is taken care of. The problem here is that simply cannot be true.
Society is made up of individual people.
If you take away the individual freedoms of each person in a society, you have effectivly reduced the freedom of the society as a whole. This is the exact opposite of what socialists claim. They claim that somehow life becomes fair with socialism, and that people are equalized, but what they would do is destroy individual will, and make every person a prisoner of the society and of the state. When faced with reason like this, the next thing out of a Socialist's mouth usually is some nonsense about mean greedy people, rich kids, silver spoons, not understanding, killing poor people, not understaning what it is like to be poor, or other emotional claptrap. The reason for this is that socialist people are rapidly running out of ammunition and support at this point.
