The Trouble With Catholic Social Teaching by Thomas E. Woods, Jr.

The salutary process by which the free market leads to an ever-higher standard of living occurs without having to threaten violence against anyone or to confiscate anyone’s wealth by force. It certainly occurs very much in spite of destructive and ill-considered campaigns for a "living wage" – carried out, all too often, in the name of Catholic social teaching – which utterly fail to understand how this process occurs and which only make it more expensive to hire people in the first place.

I mostly disagree - Woods is battling a few straw men of his own making here - but an interesting read nonetheless. Thanks to Mark Owen for the link.
