Mrs Thatcher saw that human dignity in fact resides in independence, individuality and self-determination. So she pursued the happiness of the nation by preserving the liberty of its citizens. She was routinely condemned for ice-cold brutishness by the Left, and by some in her own party. They said she was ‘money-obsessed’. But she did not accept that an interest in economics implied a heart of stone. On the contrary, she believed that individuals could not be free if they were poor and miserable. Liberty is liberty, and as the great economist JK Galbraith said, ‘The greatest restriction on the liberty of the citizen is a complete absence of money.’
