I think your husband’s view is typical for many of us. We tend to compartmentalize, which makes it easier to pick and choose, or rationalize the aspects of Church teaching we find disagreeable. I do it too.
That said, I do not think it is wise to say, “Oh, the Holy Father is just being political here. I can ignore him where this is concerned,” or, “Clearly, the Holy Father is talking about some other nation and some other economy. He can’t be talking about the good old USA!” Many Catholics said the same thing about Pope Paul VI when Humanae Vitae was issued. “Stay out of our bedrooms, Holy Father. Stick to things you know about.”
When I do this (and I sometimes do), I see it is pride at work. I’m like a little kid again, “You can’t tell me what to do!” The Church, however, teaches that no aspect of our lives, even (or maybe especially) politics and the economy, can be excluded from our life of Faith.
