Evil acts can be given an aura of moral legitimacy by noble-sounding socialistic expressions such as spreading the wealth, income redistribution or caring for the less fortunate. Let's think about socialism.
Imagine there's an elderly widow down the street from you. She has neither the strength to mow her lawn nor enough money to hire someone to do it. Here's my question to you that I'm almost afraid for the answer: Would you support a government mandate that forces one of your neighbors to mow the lady's lawn each week? If he failed to follow the government orders, would you approve of some kind of punishment ranging from house arrest and fines to imprisonment? I'm hoping that the average American would condemn such a government mandate because it would be a form of slavery, the forcible use of one person to serve the purposes of another.
Would there be the same condemnation if instead of the government forcing your neighbor to physically mow the widow's lawn, the government forced him to give the lady $40 of his weekly earnings? That way the widow could hire someone to mow her lawn. I'd say that there is little difference between the mandates. While the mandate's mechanism differs, it is nonetheless the forcible use of one person to serve the purposes of another.
Probably most Americans would have a clearer conscience if all the neighbors were forced to put money in a government pot and a government agency would send the widow a weekly sum of $40 to hire someone to mow her lawn. This mechanism makes the particular victim invisible but it still boils down to one person being forcibly used to serve the purposes of another. Putting the money into a government pot makes palatable acts that would otherwise be deemed morally offensive.
This is why socialism is evil. It employs evil means, coercion or taking the property of one person, to accomplish good ends, helping one's fellow man. Helping one's fellow man in need, by reaching into one's own pockets, is a laudable and praiseworthy goal. Doing the same through coercion and reaching into another's pockets has no redeeming features and is worthy of condemnation.
Some people might contend that we are a democracy where the majority agrees to the forcible use of one person for the good of another. But does a majority consensus confer morality to an act that would otherwise be deemed as immoral? In other words, if a majority of the widow's neighbors voted to force one neighbor to mow her law, would that make it moral?
