Neoliberalism is the idea that minimizing government impact in markets is a good thing, and that government regulation should be designed to efficiently address externalities with as little market distortion as possible.

Its bigger than that. I dont know if it was clear from how I said it, but there not being a “there” there is that both the word has lost meaning, or that its meaning has broadened to mean something bigger. You should look into some of those references I dropped.

Whatever “this” is, I think neoliberalism is a good word for it (and I do take the broad definition to include the culture behind it).
