Max Stackhouse lays out what I think is the central problem and source of idolatry in the world.
An economic system is not, in and of itself, the purpose of life. A viable economy is, however, a precondition for more people being able to live as God intends—the basis for what some have called the "Protestant work ethic," as well as for the fact that some people are called to be business leaders. These individuals are entrusted to generate and help us manage our wealth, just as doctors help us with our health, engineers with our habitat and clergy with our faith.
The Bible warns against both too much poverty and too much wealth. The poor are often forced to worry about their survival to the point of desperation and despair, while the rich are often tempted to structure society to benefit only themselves. Both lose confidence in God's providence; both damage their neighbors and society. In this sense we might say that God wants everyone to be middle class, with existential warrants for a confident hope and generous spirit.
