"There's a great deal of basis for believing that a free society is fundamentally unstable - we may regret this but we've got to face up to the facts. ... How often and for how long have we had free societies? For short periods of time. There was an essentially free society in 5th-century Greece. Was it able to survive? It disappeared. Every other time when there's been a free society, it has tended to disappear. I think it’s the utmost of naiveté to suppose that a free society is somehow the natural order of things." - Milton Friedman
