If one meets a powerful person - Adolf Hitler, Joe Stalin or Bill Gates - ask them five questions: 'What power have you got? Where did you get it from? In whose interests do you exercise it? To whom are you accountable? And how can we get rid of you?' If you cannot get rid of the people who govern you, you do not live in a democratic system.

Well, it all began with Democracy. Before we had the vote all the power was in the hands of rich people. If you had money you could get health care, education, look after yourself when you were old, and what democracy did was to give the poor the vote and it moved power from the marketplace to the polling station, from the wallet...to the ballot.

No medieval monarch in the whole of British history ever had such power as every modern British Prime Minister has in his or her hands. Nor does any American President have power approaching this

The nature of the economic system should be a matter for public choice, and free market capitalism should not be accepted without any discussion of the rich variety of alternatives ... Unlike civil laws, economic laws are imposed on people with all the authority of immutable laws of nature. But the economy is created by people, supported by government intervention, regulation, statute and subsidy, and implemented in such a way that it gives substantial wealth and power to a privileged few, while the majority face a life of relentless work, stress and periodic financial insecurity.
