It’s not that democracy makes people happy but rather that happy people are much more likely to establish a democracy. The soil must be rich, culturally speaking, before democracy can take root. The institutions are less important than the culture. And what are the cultural ingredients needed for democracy to take root? Trust and tolerance. Not only trust of those inside your group—family, for instance—but external trust. Trust of strangers. Trust of your opponents, your enemies, even. That way you feel you can gamble on other people—and what is democracy but one giant crapshoot?
