More than any other nation, the United States was founded on broad themes of morality rooted in a specific religious perspective. We call this the Judeo-Christian ethos, and within it resides a ringing endorsement of capitalism as a moral endeavor.
Spero also discusses the important example of Joseph's plan in dealing with the famine in Egypt (Gen. 41; 47).
At the end of Genesis, we hear how after years of famine the people in Egypt gave all their property to the government in return for the promise of food. The architect of this plan was Joseph, son of Jacob, who had risen to become the pharaoh's top official, thus: "Joseph exchanged all the land of Egypt for pharaoh and the land became pharaoh's." The result was that Egyptians became indentured to the ruler and state, and Joseph's descendants ended up enslaved to the state.
God begins the Ten Commandments with "I am the Lord your God" and concludes with "Thou shalt not envy your neighbor, not for his wife, nor his house, nor for any of his holdings." Envy is corrosive to the individual and to those societies that embrace it. Nations that throw over capitalism for socialism have made an immoral choice.
