Self-interest is not myopic selfishness. It is whatever it is that interests the participants, whatever they value, whatever goals they pursue. The scientist seeking to advance the frontiers of his discipline, the missionary seeking to convert infidels to the true faith, the philanthropist seeking to bring comfort to the needy - all are pursuing their interests, as they see them, as they judge them by their own values.

Milton FriedmanIf, for example, existing government intervention is minor, we shall attach a smaller weight to the negative effect of additional government intervention. This is an important reason why many earlier liberals, like Henry Simons, writing at a time when government was small by today's standards, were willing to have government undertake activities that today's liberals would not accept now that government has become so overgrown.
