" What we don’t need is central economic planning or new laws, more taxes or fewer good-paying jobs. What we need is something much more difficult to get than a Porsche—character. We need the sort of character that is able to look at the world and all it has to offer and at certain key moments say simply, “Thank you, but I’m now satisfied.” It takes a huge amount of moral stamina to be able to say, “Yes, we could afford it, but we are not going to buy it, because it does little to contribute to the basic goodness of our lives.” We need to switch our economic thinking from the supply side to the desire side of the equation.
