Why is libertarianism so infallible?

It is due to it being the application of political science. It does not permit failed policies to be continued fruitlessly year after year with idealistic fervour, it is next to impossible for anyone surrounded by fierce libertarian critics to continue clinging on to lies. It is a purely functional machine, lubricated with justice and fueled by free speech.

Socialists see 'the people' as the mass of the population. So, while Bush may intervene in the economy, it isn't socialist, because he is doing it for the benefit of an elite group within society, rather than people in general. Sorry if I am feeding a troll, it can be hard to tell when the topic of socialism comes up.
