John Derbyshire makes a good point:

That’s economics for you—and economists, and The Economist. The world of their imagination is a cool, well-lit world in which thoughtful human beings, responding to rational incentives, move along paths defined by elegant mathematical formulas. It is a shadow world, a dream of perfection. It resembles, but only as shadows resemble objects, the grimy, gamy, half-mad world of actual humanity—the substance of human affairs.

  That is why Capitalism is impossible without Objectivism.
