I think he's talking about the culture we live in and trying to  help us live in it with the gospel as our guide. Your point about him not having to shelter, feed, and clothe a family is not his immediate concern. He  is concerned about the children living in poverty or in war torn zones. He is trying to make the world a better home for everyone. Look around you. Everyone I know is complaining about having too much stuff. I have to make a conscious effect not to allow myself to be pulled into that culture. I try not to be sucked into the latest "must have". Put yourself in his shoes. He looks at refugees, war, discord. His job is to lead. And what an example he's setting. He is having an impact, not only on RCs but on all the world. When I was growing up houses were smaller, our food was wholesome but simple and we valued the things we had more than we do now. Buying someone a gift is a big problem because they have everything they need. Some problem! The pope is not criticizing you
