Roman Catholic leaders from Cardinal Óscar Andrés Rodríguez Maradiaga to Pope Francis himself have made news this year in their criticisms of supposed free-market economies, likening them to a form of idolatry that exploits and denies access to the poor. Because Catholic social teachings emphasize stewardship and aid to the less fortunate, clergymen such as Maradiaga have taken aim at perceived "structural causes for poverty."

It is in identifying these causes that the cardinal's fulminations against free markets become problematic. While he can hardly be blamed for supposing that something in relations between rich and poor is amiss, it is his faith in the positive interventions of the state that is the "deception." Ironically, the "free market" that Maradiaga so sincerely denounces is itself a product of deep and sustained state coercion on a scale not often recognized for what it is. We must therefore distinguish between two ways of employing the phrase "free market," lest we fall into the trap that caught Maradiaga - the trap of opposing libertarianism in principle without actually understanding the economic system it prescribes.

In early June, as a prelude to an expansive study of the Fortune 500 due later this summer, Citizens for Tax Justice (CTJ) published an analysis of "the current corporate tax debate." Anarchists oppose taxes on principle as an exalted form of theft, but the fact that the most profitable firms in the country aren't paying up raises other important questions.

Arguing that the "tax code has ... become overburdened with loopholes, shelters, and special tax breaks," CTJ's study demonstrates that 12 of America's largest companies currently pay, in effect, a tax rate of negative 1.5 percent. That means that some corporations - among them Boeing - are in fact making money through the tax system as it is currently operating.
