I only want to point out, in a forum that won't be filled with flying monkeys flinging poo, that this is not "papal moralism:"
“Then, on the middle class, there are some words that I’ve said — but a little in passing,” he said, musing. “But talking about the common people, the simple people, the workers, that is a great value, no? But I think you’re telling me about something I need to do. I need to delve further into this.”
It's papal pastoral care.
I know nothing about being Pope, except it's a job I never want only because I'm a terrible administrator (man got to know his limitations!). But I know something about being a pastor. Delving further into a subject is pastoral humility recognizing answers are hard, but necessary, and that things don't matter and ideas don't matter; only people matter.
Rich, poor, or middle class: people matter. Things and ideas follow from that; they don't precede it.
