economics is the science of human action. but why do markets fail at roads?
“Many people think that economics is a matter of opinions. Economics is not a study of opinions. Economics is a science, and as a science it deals with eternal laws — laws that men are not able to change — laws that remain constant. If we want to improve our own satisfactions in life, we must improve our ability to know and use these laws of economics so as to attain more of the things we want. So, if the civilized world is to survive, people must learn more about this science of human action.”
