““Each of these imperatives has a tendency to degenerate into an excuse for greed and materialism in the absence of the other. Without the call to generosity, the call to productivity makes people feel entitled to live materialistic lives—as long as they accumulate their wealth by working productively. But without the call to productivity, the call to generosity makes people feel entitled to live materialistic lives—as long as they pay off God by tithing their 10 percent. The only way to root out materialism is to reorient people’s attitudes about their entire economic lives. If you only lead people to do good work (productivity), they’ll use their wealth selfishly. If you only lead them to get their use of wealth right (generosity), they won’t orient their lives to good work. The whole life of a person has to turn away from selfishness and serve God and neighbor. As someone once said, the only effective place to intervene in a vicious circle is everywhere at once.””
