From Walter E. Williams:
While America’s liberal elite have not reached the depths of tyrants such as Lenin, Stalin, Mao and Hitler, they share a common vision and, as such, differ only in degree but not kind. Both denounce free markets and voluntary exchange. They are for control and coercion by the state. They believe they have superior wisdom to the masses and they have been ordained to forcibly impose that wisdom on the rest of us. They, like any other tyrant, have what they see as good reasons for restricting the freedom of others.
Their agenda calls for the elimination or attenuation of the market. Why? Free markets imply voluntary exchange. Tyrants do not trust that people behaving voluntarily will do what the tyrants think they should do. Therefore, they seek to replace the market with economic planning control and regulation.
