I suspect very strongly that, like Thatcher, Truss and Kwarteng are both acolytes of Milton Friedman and Friedrich Hayek.
This makes Truss an extremist.
According to Friedman's extremist (and discredited) philosophy, too much government intervention (e.g. to tax company income or the pay of top executives) prevents the free market from producing stability and prosperity. So for capitalism to flourish, the state must remove itself from all economic activity except for, in the words of Friedman ‘the military, the courts and some of the major highways’. Notably, education, health, and purveyors of energy like gas and electricity do not feature on his list.
Just playing amateur psychologist for a moment, converts are often the most zealous advocates of the faith that they embrace. As they were not brought up in it, it is almost as they have to convince themselves as well as other adherents of their fervour. And Truss is a convert to Conservatism, which means that she has to come across as more right-wing than other right-wingers.
So let's consider what she might be the equivalent of when it comes to other forms of extremism. If she was on the far left, she would want to abolish markets. When that was tried in Russia under 'war communism', millions perished from famine. Alternatively, if Islam was her faith, she would probably have embraced - not outright Salafi-Jihadism - but some kind of Islamist project like that pursued by, say, the Muslim Brotherhood. If she was a Christian, it might be something comparable to the Moral Majority blended with Ayn Rand.
Hope I am wrong but that's what I suspect that we're looking at, a starry-eyed enthusiast for market fundamentalism of the most perverse kind, one which even raises the hackles of other free-marketeers.
She needs reporting to Prevent.
