Capitalism is what people do when they are free.
Thus, it is Catholic.
Free and morally upright. Otherwise they do all kinds of things, often at the expense of capitalism.
For example, free people often borrow from willing lenders. That, the Left constantly reminds us is at the core of the American budget deficit. Indeed, a necessary component of capitalism is a banking system and banks exist in order to lend. But observe: you and I surely did not sign up for Obama's (or Bush's -- plenty of blame to go around) national debt. But me and my children will be stuck paying for it; they did not sign any notes either. How is that a life of the free nation? -- and how is that mindless, unending, not secured by anything but "faith and credit of the US government" incantation orgy of debt -- capitalism? -- and how can that be justified morally?
One day, Catholic America will wake up and then every thief will find his street lantern.
