I was responding to your request for evidence for searealist's statements that the US educational system is the best in the world when accounting for ethnicity.

But, since you brought it up: Contrary to what is often said, there is very little evidence that funding affects outcome at all. New York City spends more per student than anywhere else in the US. <https://www.silive.com/news/2019/06/how-much-does-new-york-c...> Baltimore, an incredibly poor and run-down city, spends the third most. #4-6 and #8 are all wealthy suburbs of Washington DC, but their schools are all far better than those of Baltimore or NYC on average, despite Baltimore spending slightly more per student and NYC spending 60-70% more.

(With that in mind, now reread the above Twitter thread.)
