Another way to put it might be that Americans fundamentally do not trust the state, and Europeans (or at least Western and Northern Europeans) do.
Of course, this is painting with a very broad brush, and people in both places believe in all sorts of different political ideologies, but I think it generally tends to be true. Europeans are more likely to reason along direct lines like "this is a good policy, therefore it should be enacted" whereas Americans will think in more abstract terms like "this may be a good policy, but do we really want the state to have the power to enact such a policy? How may this power be abused in the future?"
I don't have a good explanation for _why_ this is the case; intuitively, you'd expect the opposite, since the US has never had a totalitarian regime, and most of Europe has within the last 100 years. My only guess is that nowadays the US is way more corrupt, undemocratic, poorly run, etc. than most countries in Western and Northern Europe which leaves a bad taste in people's mouths.
