A random quote from the past year:
"Economies can blossom and grow only if people are deluded into believing that the production of wealth will make them happy … Economies thrive when individuals strive, but because individuals will strive only for their own happiness, it is essential that they mistakenly believe that producing and consuming are routes to personal well-being" (Daniel Gilbert, quoted in Newsweek, Oct 15, 2007).
[Update: I posted this quote without much reason or any comment. I want to add a comment: If we believe that the making of wealth itself will make us ultimately happy, then we are deluded. But I think there is a sense in which the production of wealth does/should make us happy. Our problem is that our thinking is divorced from a Christ-centric view of work and wealth and consumption.]
