Americans are allergic to any hint of 'socialism', even when it is barely so. To be honest, as of Thatcher's accelerated purge of the various homegrown nationalisms[1] that existed, the UK has been moving away from it, and the NHS and (though not 'traditionally' nationalised, as they are) our Public Service Broadcasters have been leaned on quite capriciously by her successors... One bank was sort-of-nationalised in response to 2008ish financial stuff (I think the government has divested itself of the remaining sharea it took on, a year or two ago) but the Bank Of England was also released from direct government control at some point (and all the Bank Of <Other Region>s I'm fairly sure already were non-governmental entities, but don't quote me on that) and Brown got a lot of flack for selling the gold-reserves off too cheaply (or even that he did at all, depending upon the economistic theory being favoured by the flack-firer).
...But, compared to us, the US seems to have far more "smaller and smaller government" inclinations than otherwise. I could see the situation of Snow Crash (remaining 'Federal' claves are rare non-corporately-goverened zones in a sea of microstate/megabucks mash-up, and there are requeste not to block the toilets up with dollar-value pieces of paper that are more cost-effective than genuine TP) if some segments of the political establishment get their way whilst the other segments generally don't try very hard at all to stop them...
And the distinct impression that the groundswell of support for all such hyperantinationalisations you get to see evolving in the US is very much "turkeys voting for christmas" stuff.
@McT, you ninja you: I don't think you're nevessarily being a turkey here, because I also think that nationalisation by the US is probably also going to be done in the least useful way with loads of bad ideas bolted onto it by those who would have stopped it but have switched to making any inevitable progression turn out just right for them, and I suspect that's what gives you concern also. Something like, anyway. But, yes, something like the Norwegian Sovereign Wealth Fund derived from the original oil-boom (something that the UK could have done, but didn't, in what probably turned out to be a bad decision beyond the short-term gains), except of course it would have to be something a bit more future-friendly.
[1] Absolutely all the standard utilities, Telephones, Water, Eletricity, Gas... Trains and Buses and even in some small ways the roads themselves. These days (but it started back then) also a push towards Academy-style education (both as a punishment for failing and also as a reward for not doing so!), give or take regional attitudes to Tuition Fees at the Higher level, to buck the trend. And of course Coal, but that was more like an Extinction than a Privatisation. There's some reverse
