Funnily enough, not even neoliberals believe in the free market regardless of how much they spout its nonsense.

Thatcher was one of such neoliberals, she would always talk about how people should become self-sufficient and governments shouldn’t interfere in the free market for it to truly work and so on, but during her rule she was spending billions in subsidies for corporations (aka government interference in the free market). Of course, they weren’t called subsidies in the paperwork but some other bullshit like “public investment”, but their effect was still the same.
