That's a pretty American, libertarian take. As somebody who grew up in Western Europe, I'm not disillusioned by "the state" per se, and I think that the facts rather support that privatisation doesn't always make things better (e.g. railways). None of us may be "right" (it always depends on your experiences), but it's worth considering that "using the state to fix society" isn't a completely ridiculous take for everyone.
