The Ten Commandments are the moral law of Jesus Christ. The principle of not stealing and not coveting imply individual property rights which are at the core of a capitalist economy. Yet principles against killing, lying, etc., and principles for weekly Sabbath, due honor of human authorities, etc. place clear limits on economic activity. There need to be clear moral guidelines and limits on human conduct, as well as protections for the weak, enforced by the government and taught by the church. It is definitely not Marxist, but it really is not libertarian (at least in a purist sense) either.
Sadly, the modern USA has lost much of what we historically had both in terms capitalist protection of individual property rights, but also in terms of limits for mankind's own good (we see it in legalized abortion, erosion of Sabbath rest protections, etc.). In departing from Christ as a nation, we have lost many blessings and absorbed many judgments.
