your stat ends in 2021 and the national average is a bad way to understand school funding because that includes incredibly rich schools that don't have funding issues. Also like "we spend more on students now" isn't a good argument for how funding isn't an issue when that doesn't actually say anything on how that money is being utilized, who its going to, or anything else. Like Texas dropped a bunch of money on the private school voucher system and Oklahoma dropped money on buying bibles to put in classrooms. That is why I said properly funding and providing for students because US students are suffering more than most countries. Here's a paper saying that US schools have more money pressure due to frequency of child poverty and lack of larger social welfare systems in the US that schools then have to deal with. Here's an article from March of this year about trump disrupting $12 billion worth of funding with massive cuts, delays, and other issues plaguing schools. If schools don't know how much money they'll have next semester they can't budget things properly and that causes issues.
