I don't think this is entirely true.
I think you're right that the Bible doesn't really favor capitalism vs socialism or comments directly on a number of modern issues that have arisen from modern industry, a market economy, and the nation-state, but Leviticus, Deuteronomy, and Exodus certainly create an image of an economic ideal centered on mutual cooperation, liberal lending, and debt forgiveness with a number of laws that require the community to provide a basic level of support to those in need particularly orphans, widows, the sick, the elderly, and aliens. Biblical prophets routinely criticize the people for not following these laws, and Jesus regularly appeals to this agrarian village ideal from the Torah when preaching in Galilee and the surrounding area. The Gospel writers make heavy use of these speeched and narratives during a time of economic and political crisis. I think we make a mistake by viewing these things as "morality" rather than "economic strategy" that fit the historical and geographic context. But certainly reading "capitalism" or "socialism" into the text is inappropriate.
The Bible gives conflicting views over the level of desired political and economic centralization, but I think the overarching narrative is critical of centralized political power and opposed to foreign political influence.
