One of the great mistakes is to judge policies and programs by their intentions rather than their results.
Milton FriedmanPeople who intend only to seek their own benefit are โled by an invisible hand to serve a public interest which was no part ofโ their intention. I say that there is a reverse invisible hand: People who intend to serve only the public interest are led by an invisible hand to serve private interests which was no part of their intention.
