What makes Pope Francis's attack so significant is that his position, too, is charged in moral terms.I'm not sure that position is as unusual as the gentleman portrays it to be. Generally all government action makes you poorer, and therefore has to be pitched in terms of some new capacity that you will achieve in return: and excellence of capacity is, of course, what the ancients meant by the term "virtue." Progressives promising to force you onto health care exchanges are promising to strip you of considerable wealth in return for a capacity, so far unachieved, to provide some measure of healh insurance to those the markets deem too risky to insure in an ordinary risk pool. Conservatives asking you to support the local bond referendum so they can build a new jail, and therefore lock up more criminals, are also suggesting that they will make you a little bit poorer -- in return for a society that is a little bit more virtuous, in the sense of being stronger against the presumably wicked.
What he really believes is that riches in themselves are bad for people. That is part of the reason he does not live in the papal apartments. This is not a view shared throughout the Catholic hierarchy. Nor is it really, whole-heartedly, shared by the politicians who will praise his views. I don't see any party anywhere in the world, except perhaps the Greens, running for election on the basis that they will make the voters poorer but more virtuous.
So there's always a trade of wealth for virtue, if government is meant to be the means to the end. The radical thing about Reagan's claim was that you could, by shrinking government's powers and sphere of influence, pursue wealth and virtue at once.
That "riches in themselves are bad for people" is not a position Aristotle held, nor Plato -- both held that a proper substance was necessary to pursue virtue, because it provided the leisure for contemplation. What both condemn is not wealth, but a life that focuses on wealth instead of virtue.
That riches are perilous does seem to be Jesus' position, though, and the Pope is not supposed to be neutral between these ancient thinkers.
