Yep, countries with a greater average IQ have much less people believing dumb theories (e.g about bill gates and covid-19), countries like Japan and South Korea. All countries that reduced funds for public education years ago in a short-sighted attempt to save money are seeing it's dire consequences, and now amplified thanks to the internet.
Teachers still complain they have to pay for school supplies from their pockets [0] [1], and if the money is not going to them I wouldn't really call it educational funding
Ask anyone what they think "educational funding" is and they pretty much will all mention teacher's wages among other things. The single most important thing to get good education is good educators, and to get good educators you need good wages, but I'm pretty sure you already knew that so you are just nitpicking about the exact definition of those words.
That's what they make after 15 years experience, the actual average for all teachers is much lower[0] (it is $38.761), one cause is that about 30% of teachers leave the profession less than 5 years later[1]; for example the average pay for a teacher in NY is 45K, one of the most expensive places to live in the US. According to the OECD itself teachers on the US have one of the longest working hours[3] in the world, this unpaid overtime means money lost due being unable to have a second job or due incurring in costs directly related to lack of time (e.g. eating out thanks to having no time to prepare lunch); the cause of this overtime seems to be lack of prep time in the instructional day as teachers are expected to be actively teaching for most of the day, and are provided woefully few hours for planning, correcting, and collaboration [4]
