The “tragedy of the commons,” as exposed by economists, is as follows—the commons being a collective property, say, a forest or fishing waters or your local public park. Collectively, farmers as a community prefer to avoid overgrazing, and fishermen overfishing—the entire resource becomes thus degraded. But every single individual farmer would personally gain from his own overgrazing or overfishing under, of course, the condition that others don’t. And that is what plagues socialism: people’s individual interests do not quite work well under collectivism.
