I'm not a historian but my understanding is that Goldwater was the first major Republican candidate to go big on the whole "the government can't solve problems, the government is the problem" political meme, when he ran for president in 1964. Meaning, the notion that governments doing stuff, any stuff, is inherently bad. It dovetails somewhat with libertarian thought but only in the most handwavey, BS ways possible, because somehow the result is always less fiscal responsibility and even more wasted money. Republicans have leaned on this talking point hard ever since then, in part to justify tax cuts for their donor class (but not spending cuts, ironically). They also use it to justify inaction, because if the government takes action, then that's the government "doing something", which is bad, get it? This is a much easier argument for them to make than actually coming up with alternate solutions to things. It's nihilism disguised as trying to save people money, but the reality of the last 56 years has been lower taxes for their donor class coupled with vastly increased government spending, which is the opposite of anything resembling fiscal conservatism.
