The educational experience of students is not dictated wholly by teachers, curriculum, and facilities.
You seemed to disagree with his claim. Due to this apparent disagreement, I interpreted "intrinsic" to mean something other than teachers, curriculum and facilities. The Chetty paper, and the entire need for VAM (as opposed to just measuring raw test scores), shows this to be true. Do you believe this to be false?
For example, the kid's quality of life outside of school. Which is demonstrably improved by helping poor kids with rent. Which I believe he is trying to argue against.
I may be misreading. I'd like a second opinion. I'd rather not assume people I'm arguing with hold revolting core beliefs. This would not be, like, the first time I'd jumped the gun on something like this: I myself hold a (probably faulty) core belief that the median HN participant is likely to host retrograde beliefs about race, which is unfair of me too.
If you want a summary, I don't share your religious faith that God ensured an identical statistical distribution of genes across all subpopulations when he created man. But Kalium's argument is not dependent on this - there are more things in the world than simply teachers, curriculum, facilities and genetics. For example, poor people might be disproportionately bad parents (perhaps they exhibit many bad behaviors which also make them poor) and this might cause their children to be disruptive in school.
That's a concrete theory that's directly compatible with your secular faith in statistically identical genetic distributions, but still supports Kalium's claim.
And have you also "discovered" a correlation between this academic performance gene and melanin content? Or gender too? Surely you don't want to deprive us of such important "discoveries".
