I wonder how that dynamic will interact with the decreasing need for adults in the workforce.
In addition to that, I think it's clear that there's two curriculums at school: a spoken one and an unspoken one. The spoken curriculum is math, science, reading, etc. The unspoken curriculum is mass social indoctrination around conformity, complacency, and willingness to do boring work with minimal reward for long periods of time. Essentially, to psychologically prepare children for the realities of work life.
This is basically what I'm saying; educational requirements are an easy way to track the workforce. At the end of the wars, the labor market contracted hugely (as those soldiering jobs went away), so our society cut the least valuable workers out of the workforce. That it had humanitarian justifications, in that those workers also had the least personal agency and influence over their working conditions, is almost coincidental.
Compulsory education in the US started in 1852 in Massachusetts and ended in 1918 in Mississippi:

The first modern compulsory education was enacted in Prussia in 1763.
One boy's mass social indoctrination is another boy's ultimate fuck party.
Personally, if my 22 year old self travelled in time three years backwards to meet 17 year old me, and then travelled 20 years forward to present day to me current me, I have no doubt 18 year old me would the odd man out in this triplet.
In the same way that there isn't much practical (i.e. economic) interest in tailoring schools and college classes to people with different daily cycles, there isn't much interest in teaching people about common problems ahead of time, or running some kind of continuous life challenges training that could potentially do a lot to improve life quality.
In my 50s, one of the common problems my friends have is dealing with parents who are either dying, recently dead, or have a terminal illness like Alzheimer's.
Of course that happens to younger people too, but there are actuarial peaks where it becomes massively more likely that you'll be dealing with a certain set of challenges in a certain decade of life.
There's shockingly little information around about some of these challenges. So it's incorrect to assume that the learning ends after school or college.
You won't learn anything about dealing with these challenges there. You won't even be warned they exist.
Does it make his nebulous conspiracy theory more or less believable that you somehow think the age at which we stop warehousing kids actually has nothing at all to do with physical maturation?
You specifically selected parts of the body that finish maturing earlier than my statement, because it was the most controversial thing that popped into your head. It didn't pop in to your growth plates, it didn't pop into your elbow. It didn't pop into your left middle toe. It popped into your head.
You should allow these very statements to marinate in that same head, and see if you can come to the correct conclusion as to which part of your body I was referring to in my original comment.
If you look at post-industrialization patterns, the age at which humans become productive has been increasing as the productivity of humans has increased. On a subsistence farm, a 6-year old can be doing useful work to increase the productivity of the farm. In a coal mine or factory, an 8-year-old can do productive work. 16-year olds can do construction, food industry, but for jobs with decision-making responsibilities (as more and more jobs are today), we don't trust anyone under 22.

this is on my eventually 2 read list
Our society decided humans become more valuable when they are given the opportunity of a childhood filled with education instead of manual labor.
US student loan debt is somewhere around $1.4 trillion. For comparison, mortgage debt is somewhere around $8.9 trillion. That's a pretty damn big market. [0][1]
If that education was free, I'd wholly agree with you that it's simply our society deciding this is for the betterment of all. But when you combine these two sources of debt (student loans so we can get jobs that afford us home mortgages) then we're looking at a new, weird, first-world form of debt bondage. [2]
Again, I realize that's a very pessimistic point of view. Will be interesting to see how the history books view it in years to come.
