Adam Smith's key insight was that both parties to an exchange can benefit and that, so long as cooperation is strictly voluntary, no exchange can take place unless both parties do benefit.
Milton FriedmanTo the free man, the country is the collection of individuals who compose it, not something over and above them. He is proud of a common heritage and loyal to common traditions. But he regards government as a means, an instrumentality, neither a grantor of favors and gifts, nor a master or god to be blindly worshipped and served.
Milton FriedmanI want people to take thought about their condition and to recognize that the maintainence of a free society is a very difficult and complicated thing and it requires a self-denying ordinance of the most extreme kind.

Milton FriedmanThe only reason there is a crisis about Social Security in the US and pensions in Europe and Japan is that you cannot maintain a "Ponzi" scheme indefinitely. We have collected from today's young to pay today's old and counted on tomorrow's young to keep doing so. That was a fine scheme as long as the number of young people was rising faster than old people. When that ratio comes to an end, such a system also has to end.
