During a long flight home from Paraguay to Rome in July, after a South American tour full of jeremiads against global capitalism's ills, Pope Francis admitted to reporters what he really thinks about economics.

"I have a great allergy," he said, "to economic things."

He talked about his father, an accountant struggling to get by. The pope remembers him hunched over his ledgers, even at home on Sundays. Those numbers took his father away from their family and interfered with the Sabbath.
