Ultimately, the debate about choice is not about markets but about character. Liberty and responsibility really do go together; it’s not just a platitude. The more freedom we have to control our lives, the more responsibility we have for how they turn out. In a world of constraints, learning to be happy with what you’re given is a virtue. In a world of choices, virtue comes from learning to make commitments without regrets. And commitment, in turn, requires self-confidence and self-knowledge.
