There needs to be CVEs/KEV for public misinformation vulnerabilities. APTs have been using social media channels to spread disinformation, the CDC has been disabled by another APT, and we're failing to immunize people against health misinformation.

Far from from 'most', we find literally none except for Luxembourg ($33k), which being an extremely wealthy and tiny nation is not that much of a surprise; and is otherwise an extremely outlier.
On the other hand, the UK, France, and Germany are all beaten by Alabama [yes, that bastion of education], at $15k PPP (you can't, of course, forget to apply PPP calculations to the US states you are looking at if you're going to apply them to European countries). This is, btw, very consistent with the average income in these areas, too - Alabama is around or wealthier in PPP terms than the UK, France, and Germany as well.
