Adam Smith (1723–1790), author of The Wealth of Nations and one of the greatest economists of all time. When Smith could not finish teaching one semester, he told his students he would refund their tuition. When the students refused the refund saying they had learned so much already, Smith wept. We, however, will not refund the purchase price of this book even if you read only half of it. We are not as good economists as was Adam Smith.
