A slave can escape though. It's all a matter of degrees, and where one draws the line between 'slavery' and 'freedom' depends entirely on one's world view. Personally I believe the crucial element is the psychology of a human being, and I believe that by that measure, 'true' freedom is much rarer than we think.

On the level of societies, I think a world where everyone would have too much freedom might actually not lead to optimal individual or collective happiness, and I think finding the balance is incredibly complicated.

All that said, I think the relative lack of security and freedom for many people in the US is a travesty and not fitting for a country that puts freedom front and center.
