That is consistent with other international measurements: https://nces.ed.gov/fastfacts/display.asp?id=1. For example, the U.S. is one of the top performers in the world in the 4th grade literacy--behind Hong Kong but ahead of Macau. In 4th grade math, the U.S. isn't as good, well behind Hong Kong, Singapore, and Japan. But still comfortably ahead of Germany, Italy, Spain, and France.
That’s why sober and clear-eyed countries like Germany conventionally sort students into tracks starting around age 10.
It really isn't. Every student should have access to quality education that meets them at their level and challenges them. Money spent doing that is not wasted on the vast majority of students. We do not need to have trash tier schools for the majority of the population so that a select few can get better ones.
Identifying where students are at and what their needs are is a good idea that would enable kids to be moved to classes where teachers can work with them at their level. It doesn't necessitate refusing a quality education to anyone. Even students with special educational needs and disabilities deserve a good education.
When students are placed in classrooms according to their level it means that no teacher is pulled away from gifted kids, because those gifted kids have their own teacher working with them. It doesn't mean that children who aren't gifted can't get a high quality education. Putting kids in a class too far above or below their level is not delivering a quality education to them.
Giving every child an environment where they can learn to the best of their ability is expensive, but it's nowhere near as costly as not doing it. Uneducated illiterate children become uneducated illiterate adults and voters. It's not a coincidence that most prison inmates are functionally illiterate. Having a good education enables more children to have a successful future.
There’s a real question of how many resources and what kind of ROI you’d get from trying to educate that bottom 20% to the same level.
I saw this play out when I was in school: profoundly intellectually disabled students getting 1:1 or even 2:1 teaching, trying to get an 18 year old to be able to read 3 letter words, while AP classes were bloated to 30+ students.
The US is the richest nation on Earth. It can easily afford to educate its people. If you really think we'd need to find new sources of tax dollars to fund that, I have a whole lot of suggestions for where to start and I'd bet that you can easily think of a few low hanging fruit yourself.

The ROI is massive. As I've said elsewhere, uneducated children become uneducated adults. Adults who vote. Adults who, if they lack the education needed to live successful lives, end up costing society in many ways over far more years than they spend in school.
I don't know about you, but I want to live and work with people who are educated and literate. If I were looking to move to another country for work, I'd want to move somewhere where the people were educated and literate. Especially if those people were going to be my boss, or my neighbor, or handling my food, or in charge of my visa application. Having a well educated population is pure win. The cost of ignorance and a lack of the kinds of skills a good school teaches is staggering.
The question is whether anyone actually expects the outcomes to change if we throw even more money at the problem, or if it'll just get gobbled up by teacher's unions, administration, and silly things like non-phonic instruction or DEI programs.
Isn't it funny how nobody ever worries about how much that's going to cost, no matter how unnecessary there's never any effort to make sure that our warmongering is funded before burdening taxpayers with it. Seems like a ripe target for some tax savings.
Longer/better educator training both increases skills/outcomes and is a gate for the poorly-suited. Higher pay makes the training seem worthwhile and increases stickiness/tenure.
