a. Quantitatively
- Reading: Canada is 3rd, America is 24th
- Science: Canada is 7th, America is also 24th
- Math: Canada is 9th, America is 39th
^ There should be negligible differences between them given vast similarities.

b. Qualitatively - Meet and talk to enough people from Asia (Japan, China, Thailand, Korea, Vietnam, China) and Europe (Iberian and Eastern) & UK. And then talk to many Americans from anywhere other than from the coasts. Conspiracy theories, misinformation, MAGA, and QAnon are the mainstream norm rather than the exception. The difference is: they don't have government censorship, a totalitarian regime, or social credit habits as an excuse for their ignorance. There are billboards with borderline racist MAGA slogans in the South US.
One country has borderline racist MAGA slogans. The other has Han Chauvinism and forced propaganda for a totalitarian state. There's plenty of conspiracy theories and misinformation in both countries. Here's a study showing that 13.8% of people in China considered GMO foods as a form of bioterrorism targeted at China[1].
I'm not saying America doesn't have problems, but most of the criticisms you lobbed at America can just as easily be lobbed at China, and yet China seems to be economically expanding rather rapidly relative to America or most places. I'll also say being highly educated isn't all roses, every country with tertiary education levels as high or higher than Canada's has a well sub-replacement birthrate - the education levels you idealise aren't even independantly sustainable.
>The reason is Americans, in aggregate, are under-educated compared to the rest of the world
Objectively wrong. It's one of the most educated countries in the world, just mediocre compared to the rest of the OECD. They're more educated than China, no matter how well a small number of urban Chinese students do on international standardised tests.
