"Many Americans have not heard of the commons except in connection with the word “tragedy.” We’ve all heard the famous tragedy of the commons parable. It holds that any shared resource invariably gets over-exploited and ruined. Since the “tragedy meme” appeared in a famous 1968 essay by Garrett Hardin, it has been drummed into the minds of undergraduates in economics, sociology and political science classes. It serves as a secular catechism to propagandize the virtues of private property and so-called free markets.
Thanks to the tragedy smear, most people don’t realize that the commons is in fact a success story – that it is a durable artifact of human history, that it is a way to effectively manage shared resources, and that it lies at the heart of a growing political and cultural movement."
