In my opinion, a forced virtue (aka a legislated virtue) is no virtue art all. Therefore, a socialist form of government is not Christianity. It's not even a reflection of Christianity.
For those who really want to understand socialism, you need to understand the economics behind it. A socialist government requires a central bank, or the support of private banks. For example, the US has a central bank which is comprised of several private banks. At the macro finance level, the goal of the socialist is to control the economic system. Therefore, all monies that are pent and all monies that come into the treasury are under their control.
If you are a private bank who controls a treasury (as in the case of the US Federal Reserve), socialism would be the pinnacle of success. This is the case because all spending dollars for all business and industry would be controlled by government. Since all government spending under our central bank system is managed in the form of a loan that is repayed in tax dollars, all spending in a socialist state becomes an interest earning benefit to the private bank that controls the monetary system. The more things are socialized, the more the bank will profit.
The same argument goes for privatizing government. Privatization is nothing more than legislating the funnel of funds into a private account instead of a federal account. It looks great on paper (reducing government etc) but in reality, what's happened is that our tax dollars are funneled by decree into someone's profit statement. Instead of privatization, the government should be controlling costs by exponential size and scope reductions, not providing our tax dollars as someone else's profit. They call it privatization but in reality, it's socialism. The conservatives around here who support privatization should chew on that for a while. You wouldn't be my first audience to do a complete "about face" on your views of the subject.
So socialism is not Christian. It may be the legislation of certain Christian concepts, but there is no salvation in following the law. But even worse, the ultimate goal of socialism is to transfer wealth from the people and from the state into the pockets of those who control the finances. it looks great that everyone has an apartment and a meal, but it's all under the thumb of the group who controls the economy. Socialism. therefore, is the antithesis of individual liberty, in 100% opposition to the intent and implementation of the US Constitution.
