The US is incredibly thin on socialism, even nominal socialism, and we already see traces of this when public-interest arguments become convenient. The Net Neutrality fight is a hideously good example; once ISPs decided their monopolies were too blatant to use free market rationales, they went out and astroturfed a narrative where cheap and fair internet was an attack on minorities and the poor.

And yes, I can't deny that US libertarianism (the party and a lot of the individual voices) is weirdly pervaded by a willingness to abandon libertarian principles in deference to corporations. It wasn't that long ago that you could find conservatives complaining about excessive "civil libertarianism" in calls for social progress. Today, it's horribly easy to find people arguing that Wells Fargo should be allowed to stretch their forced arbitration clause to cover outright fraud, because apparently the bank's rights are the only ones which we need to protect.
