What specific things apart from US abortion laws are 'American' in nature? If it means McDonalds outlets then fair game, but I can't think of anything else, apart from maybe the US 'hustle culture' that is always admirable.
Is it?
When I moved to the US, I was surprised that working multiple jobs, or working seemingly physical jobs after 65 or even injured, e.g. as your typical Home Depot associate, were quite common.
For such a wealthy country, it's disgraceful.
And it has always surprised me how much French TV news for example love to report on what happens in the US. To a large extent, it may be just a historical bad habit or quirk (I mean as opposed to reporting on what happens in the rest of the EU or in China for example) but it's still there. So it's not exactly what americans think of as their strengths that makes it through.
America: "I don't think about you at all."
