Most important of all, you’re arguing a completely different point than what @osaka35 was talking about.
1.I'm not
@osaka35 , we don't share the same mind or thoughts, or overall political position . I can make my own separate arguments if I so choose to do so. Mine's a separate but related topic.
Oh please. The decline in quality far preceded any noticeable decline in funding

"These districts eventually realized gains in student achievement and attainment. Our preferred
estimates imply that increasing operational spending by $1,000 per pupil increased test scores by
approximately 0.15 of a standard deviation and graduation rates by approximately 9 percentage
points."
https://edworkingpapers.com/sites/default/files/ai19-58_v1.pdf
"A $1,000 annual increase in foundation funding, or 10% increase in
expenditures, yields a 0.1 s.d. increase in reading scores and a near 0.08 increase in math. In
addition dropout rates decline, graduation rates marginally increase, as does college enrollment
and to a smaller degree graduation"
yes it does follow.

When the 2008 crash happened, it made the issues that already existed, far worse. It made parents foot the bill, who already were not capable of handling that. That's why we had a decline in quality lagging behind funding, and the drop of funding making things substantially worse. Parents are going to value keeping a home and at least food on the table at number one priority. Which meant for the people who still had a home. They still provided funding on a local level. Even if it comes at the cost of unable to provide supplies for school.
As an additional tidbit of information, you will note that SAT
SAT's have been realized as a extremely flawed scoring system. Primarily because often the SAT's require very specific answers, to general problems. As in a problem that can be solved in multiple ways, but the scoring system only expects two methods of answering it. Meaning people who get the right answer, sound on every level, but didn't do the "correct" method would be dinged on the test pretty commonly. They're also attached to the very same problem.
Parent's capability to provide (financially) materials to help, in a already struggling situation. At the high school I went to (graduated in 2020 from high school) if I remember right. You had to pay to be able to try out the test. And purchase resources to study it. Not something you can easily do if your cutting it extremely close.
additionally
I say almost, because curiously, Asians continue to score higher and higher, with only a small dip around 2016
Asians and white people generally make up the upper margin of income. While other races generally don't. The reason Asians and white people do better, isn't because "They're just doing better"
And it's not because Asians are magically smarter, or white people being massive brained.
White people I don't think I have to explain the historical context as to why they're doing better. (hello racism and slaves, and knock on effects from generations of pay inequality and red lining)
Asians were previously treated like dog shit. For a while they were treated like idiots, primarily because of US propaganda. Which that same method later on (US propaganda) created the sterotype that Asian's were super smart. And as a result, reduced racism towards the group. Which also meant knock on effects generations later, as employers didn't turn them down, pay them less, or treat them as shittly as other workers. Meaning many many, generations later, they came into the position of being paid somewhat better. Which meant having the resources needed to do well on the SAT. (aka expendable income for studies)
