I see that the pope has decided to weigh in on economic issues:
“Some people continue to defend trickle-down theories which assume that economic growth, encouraged by a free market, will inevitably succeed in bringing about greater justice and inclusiveness in the world,” Francis wrote in the papal statement. “This opinion, which has never been confirmed by the facts, expresses a crude and naive trust in the goodness of those wielding economic power and in the sacralized workings of the prevailing economic system.”
A few reactions:
First, throughout history, free-market capitalism has been a great driver of economic growth, and as my colleague Ben Friedman has written, economic growth has been a great driver of a more moral society.
Second, "trickle-down" is not a theory but a pejorative used by those on the left to describe a viewpoint they oppose. It is equivalent to those on the right referring to the "soak-the-rich" theories of the left. It is sad to see the pope using a pejorative, rather than encouraging an open-minded discussion of opposing perspectives.
Third, as far as I know, the pope did not address the tax-exempt status of the church. I would be eager to hear his views on that issue. Maybe he thinks the tax benefits the church receives do some good when they trickle down.
