The ideology developed by british prime minister Margaret Thatcher over the 80's, which may be seen as the final offspring of the long tradition of British conservatism.

It was basically an extreme form of economical liberalism, relying on the assumption that in a totally free-market society, both production and distribution of goods and services reach an optimum. Only the foul and the lazy would be left aside, and therefore should not be helped in any way.

Well, that was the theory. In practice, the good old habits of authoritarianism quickly re-emerged whenever the government thought necessary - that is, quite often. It soon became obvious that the global policy was in fact more akin to right-wing conservatism than to anything else.

The result was quite ugly. To be honest, it is said that the previous Labour Party government had already made things very bad.
