"The art of economics consists of looking not merely at the immediate but at the longer effects of any act or policy; it consists in tracing the consequences of that policy not merely for one group but for all groups.
The question is not whether economic progress makes people happy. It makes them happier than they would otherwise have been. Most mothers feel happier if their children survive, and most people feel happier without tuberculosis than with it.
We often hear that various government policies are justified because "the people want" this or "we want" that. This belief assumes that dissenting minorities don't matter at all. "We want" is usually nothing more than rank majoritarianism.
