Sadly, most Catholic conservatives, especially in America, will probably respond to this by saying that the Vatican doesn’t know anything about economics and should stick to issues it understands like abortion and same-sex marriage.

If people like George Weigel, Paul Ryan, John Boehner, etc actually take this seriously, I would be very happy. But I would also be very surprised.
