Richard Land argues the case that free-market capitalism is the economic model that most closely fits in with Christian anthropology:
When I lived in England as a Ph.D. student, I was visited during my first fortnight in the country by a fellow student seeking to sign me up for the Socialist Club. In some wonderment I asked him, “Why would you think I would want to join the Socialist Club?” He responded, “Well, I’ve been told you are a Christian minister, and if you are you would have to be a Socialist.”
I responded that if I am a Christian who believes the Bible is the truth, I couldn’t be a Socialist and be intellectually consistent.
Why? The Bible tells us men are fallen, sinful and selfish. Socialism is based on the premise that individuals in particular and as a whole are at best good, and at worst neutral. Thus, Socialists believe men will work according to their ability and receive according to their need. But the overwhelming majority of human beings only do that grudgingly and then only when forced by government coercion. Such coercion never produces the productivity and innovation produced by a capitalist, free market system.
