I think the school->prison pipeline is a real issue, but I think a poor quality of education is a much bigger deal because smart, educated people generate exponentially more wealth since the industrial revolution. If you want what is best for everyone, you would focus more resources on top-performing students rather than less! Sure, top-performing students would turn out better than mid-performing students—even with fewer resources—but that's a tautology and an emotional appeal. I think the tricky part is to make sure top students give back to society once they graduate, but that seems more of a cultural issue to solve. Boring students to death probably doesn't help, though.
Now, you brought up that national testing + placement would mostly reflect socio-economic status. I think this is concerning because it lead to in-groups reinforcing themselves, which naturally decreases motivation for future rich people to help the rest of society. However, we already have examples of placement tests, and this isn't what happens! NYC has several "specialized" schools, including one of the best high schools in the nation, Stuyvesant. Admissions to Stuyvesant are entirely based on your rank on the SHSAT, yet 48% of their students are "economically disadvantaged" according to USNews. I'm not entirely sure what that means, but I would expect lower or lower-middle class. This data also matches up with my intuitions: although intelligence is heritable (through genes or upbringing), there are exponentially more "economically disadvantaged" people than rich people, so even though rich kids are overrepresented, they are still outnumbered by poor(er) kids.
Also, keep in mind that rich people will always be able to pay for private schools or tutors if they find public education lacking. So, you are really only depriving poor students of any possibility of a good education by lumping everyone together, which is worse for reinforcing classism. As you mentioned, charter/private school outcomes are so much better because they work pretty hard to cherry-pick kids that lead to better oucomes. Why not give everyone that opportunity?
That's a little facetious, because not everyone has that opportunity. Some people are just not genetically predisposed towards exams, or they're being abused at home, or they have to work after school to buy food for their younger siblings. But, it doesn't really matter why someone cannot do/be better if we're unable to fix the why. Until it can be fixed, the problem is just a part of them and they'll be punished for it. This isn't very sympathetic, but it's the game-theoretical optimal approach for getting to the Pareto frontier.
You mention that blame/punishment essentially never works, which is probably because humans are not perfectly rational agents. Sure. I've definitely seen this when I play Risk online. You have to use different strategies when people are irrational/prone to mistakes, e.g. with novices it's usually good to make a big stack and wait for everyone else to noob-slam, while with masters it's better to work with the othe rplayers to slowly choke out the rest. Optimal strategies may be less tolerant to mistakes, and a common mistake humans make is, "this person hurt me, so I will hurt them even more," without considering why they were hurt. A common theme I saw in school->prison pipeline studies is that youth get disaffected with society/the justice system, so they end up committing more crimes. If people really are being irrational, in such a way that punishment will not work, you really only have three options:
1. Force them into rationality.
2. Rehabilitate them through positive reinforcement.
3. Eliminate them from society, e.g. sending them to Louisiana/Australia, prisons/executions, or closed communities.
I'd argue that you should take whichever option is best for society, i.e. costs it the least. Why?
a) Societies cannot be comprised of mostly (weighting by utility) negative-externality people for very long.
b) Everyone else is better off by eliminating such people, thus they are motivated to do so in whichever way is cheapest.
If it were cheaper to just execute all criminals, or commit horrific human rights disasters to make prisons cheap to run, that's what society should do. Historically, that's what societies have done. Nowadays, it probably isn't cheaper; even if the average inmate spends just as much time in prison as out of it, they are probably close to net-positive to society. The cheapest solution probably is rehabilitation for most people except the unfixable, and even there, life in prison is probably cheaper than execution.
So, I think I agree with you about rehabilitation, but probably not for the reasons you cite. I think "people being products of systems" is a rather naive take; if people were products of stable systems (in the physics sense), punishment actually would work. Conservatives have a bias towards everything being a stable system [which is true; you are exponentially more likely to end up in more stable (determined by transition probabilities) trembling-hand/thermodynamic equilibria], which is probably why they're all pro-punishment and such. Note that rehabilitation can still be cheaper, but at least punishment would work. It's only when you have unstable systems that punishment might not work at all. It's a little worrying to think that America's system might be unstable right now, but the race riots and past two elections kind of show it is. More accurately, it's too easy to transition out of its current maximum for punishment to really dissuade future malcontents.

Alright, let's return to education. I think we're in agreement that:
I) The school->prison pipeline is real.
II) Imprisonment is expensive, probably moreso than rehabilitation.
As I put at the top, we probably disagree that:
III) This cost is more than that of a poor education system.
I think rehabilitation through the education system is far more expensive. Here's just a back-of-the-napkin calculation. Suppose that all inmates are directly a result of the school->prison pipeline. It costs ~$70bn/yr to incarcerate them, but let's also assume we're missing out on 2 million people * $65k/yr = $130bn from jobs they could be working. This amounts to about $200bn/yr in costs to society.
Now, the number of billionaires increases by about 36 each year, and the average billionaire has $7bn. If a better education were to double the number of billionaires produced each year, this would entirely offset the cost. Of course, billionaires are usually better at capturing value than producing it, but at least some educated STEM guy below them is producing the value. I think this is entirely doable by expelling more students. In fact, I think the justice system will only start costing more than the wealth generated from better education (through the top students) once the pitchforks and torches come out.
Similarly, we should be able to do a cost-benefit analysis on teacher salaries. In reality, the most efficient use of money is to pour it into the top schools (and have entrance exams), but the metrics don't look as good. Most legislators care about the quintiles, not the top 0.1%, plus the wokists hate inequity. And, even bottom schools need much better teachers than are currently around. That's why I want to raise all salaries to $300-500k/yr.
You mentioned that only $236bn is spent on ~4m teachers, but there actually is another $600bn going elsewhere. If you want an average class size of 20 students, you only need ~2.5m teachers, so it should be possible if you strip everything else to the bare-bones. My elementary school class was taught in a portable, and I think that's better than having a shitty teacher.
You've done a lot of thinking here, but if you did 80% of the thinking and 20% of the reading you'd reach better conclusions. There are systems that spend more per student than the US does, more % of GDP than the US does, they have lower classroom sizes than the US, they have better systems for gifted students, their students spend more time in class, they pay teachers professional salaries, they have more state of the art instructional programs, etc. etc. etc. None are trending towards the outcomes you're suggesting; in particular the EU isn't producing more billionaires (this is a product of income and wealth inequality, not educational system efficacy).

I can't imagine what you might mean by negative-externality people, but whatever it might be let me inform you there are lots of countries/governments/societies in the world that aren't doing so hot, and they've been doing not so hot for quite some time. Is this some kind of quasi-rational-market hypothesis for societies? Nowhere is this true. Why do people stay in abusive relationships? Why did Black people continue to live in States that practiced segregation? Why do people still eat unhealthy food, or smoke, or drink?
> If it were cheaper to just execute all criminals, or commit horrific human rights disasters to make prisons cheap to run, that's what society should do. Historically, that's what societies have done.
I think relying on the actions of governments who knew almost nothing (Earth is flat, what is air, diseases are punishment from God, the sun revolves around Earth) is a bankrupt argument. Governments have almost never been data-driven. Reducing the rubric of how governments/societies should act to "do whatever's cheaper" is... so wrong I don't even really know where to start. How do you justify investments? How do you justify things like entering WWII or The Manhattan Project? How do you know what's cheaper or will result in the most gains ahead of time? This can't be a real argument. Are we about to go the entire history of how governments work? I refuse. Do more reading.
> I think "people being products of systems" is a rather naive take; if people were products of stable systems (in the physics sense), punishment actually would work.
Punishment doesn't work. Deterrence is a myth, and recidivism rates are off the charts. Again you're naive to the criminal justice system. If we don't think better systems/environments lead to better outcomes and worse systems/environments lead to worse outcomes, why are we trying to improve the US educational system at all? A kid's educational attainment is preordained right? Even if you think this is a straw man, it does us no good to consider "some kids just suck" when building an educational system, again because of the School-to-Prison Pipeline where bad outcomes are so lopsided.
> Similarly, we should be able to do a cost-benefit analysis on teacher salaries. In reality, the most efficient use of money is to pour it into the top schools (and have entrance exams), but the metrics don't look as good.
Your argument relies on the prospect of these super students increasing GDP so much we offset the cost of shunting tons of students into the School-to-Prison pipeline. Not only is there no evidence for this, it's a deeply immoral system. I refuse to even continue considering it.
To be pointed about it, I have people in my family who are special needs. I myself was disruptive in school because of life circumstance. When you advocate literally for imprisoning me and members of my family, at some point I have to recognize we're fighting. I've reached that point now.
> I can't imagine what you might mean by negative-externality people
Google is your friend. Essentially, in a counterfactual universe where they never existed, the world would be better off. If you have more negative externalities than positive externalities, your society is draining wealth, and will eventually disappear.
> Punishment doesn't work. Deterrence is a myth, and recidivism rates are off the charts.
We've already gone over this. Go rehabilitate, I don't care. Just rehabilitate people in a way so they aren't actively commiting crimes against education.
> Your argument relies on the prospect of these super students increasing GDP so much we offset the cost of shunting tons of students into the School-to-Prison pipeline. Not only is there no evidence for this, it's a deeply immoral system. I refuse to even continue considering it.
You are trying to coerce one group into sacrifcing enormously for another group, and you say my system is immoral? If sacrifices have to be made (they don't), why do you get to choose who bleeds on the altar?
Also, there is plenty evidence that super students do offset the cost. For example, North Korea's system puts disproportionally more money into their top students, and they usually rank higher on the International Mathematics Olympiad than every European country except Russia. The benefit is mostly for their defense: they really needed nuclear weapons, and they couldn't get them without investing in their best students. They might not even exist as a country today if they didn't do so. What could be more beneficial to their society?

Look, everyone acknowledges Europe has a stagnation problem, America is better for startups, and the USD being the principal reserve currency makes Americans richer. You cannot directly compare countries like that. I know you're smart enough to recognize that, so I'm astonished you wrote this down.
Ideally, you could just randomly assign two policies, and see which works better. But in the real world, pretty much all studies in education are surveys, and it's hard to account for differences in space (countries/culture/socioeconomic status). Even differences in time (when new policies are introduced) have confounders, but less so. If you look at those studies, you'll find that new policies that throw money at smaller class sizes or higher-quality teachers lead to better educational outcomes. It's uncontroversial to say that better educational outcomes lead to better salaries, and higher wealth generation. (BTW, I'm not using wealth to mean USD, I mean quality-of-life. The USD is just a convenient proxy. Not sure if that was clear earlier.)
Tracking is more controversial. However, the one study that did just randomly assign tracking to 120 first grade classes found it benefited everyone:
https://www.educationnext.org/tracking-improve-learning/
Most other studies use standardized exams (e.g. the PISA), and let me remind you, those are not difficult enough to see improvement for the upper percentiles! You flippantly dismissed it, but it's a huge deal. If your national assessment were the AMC 10/12 the bottom 50% would all score zero points (really 37.5, but that's irrelevant), and tracking would look like a resounding success if the top few thousand showed improvement.

This upsets me. Have you, this whole time, only been arguing for your in-group? Every time you said, "what is best for society," did you really just mean what is best for the people you care about? I, too, want what is best for my in-group, but I've tried to talk about how ranking/expulsions/etc. would increase wealth generation, and improve everyone's quality of life.
Quite frankly, your in-group needs my in-group, not the other way around. If we really are just trying to capture value for our in-groups, people in mine could just give up on public schools and go home-school their kids. I don't think this is optimal for either of our in-groups, but you have to acknowledge that if you want certain people to go to public school, you can't be defecting against those very people! If we really do have a conflict between two in-groups, why do you feel entitled to anything from the other side?
You've mentioned the school->prison pipeline, and how a lack of education brings out the pitchforks and torches. This is entirely true on the other side as well. As you saw in the comment section, a lot of smart people literally feel like school was prison to them. They were bullied, abused, had no freedom, etc. We've both acknowledged that bad students may become disaffected with school and society (if we don't rehabilitate properly), but only I've seemed to recognize that good students will too. Perhaps the difference is, disaffected bad students become violent, while disaffected good students become quantitative traders. Well, guess what? If your entitlement comes through a threat of violence, the correct response is to eliminate that threat.
Maybe you are alright with threatening violence, but I'd rather we not fight. And we don't have to. Society holds itself together through mutually beneficial deals (and a plethora of convenient lies). The minimum I'm asking for is for public schools to be mutually beneficial. This is why, although I think it is best for society to put extra resources into their top stuents, I am okay spending only equal resources.
