Yeah, I knew that and should have written that in my comment. You are right.
I’m from Germany where this kind of inequality is particularly egregious. The explanation is probably that the fate of students is decided early on, in fourth grade. (You continue in one of three different types of schools after fourth grade, depending on your grades. Switching between schools is a hassle and only the highest school has a clear path to all universities.) Looking back at my own experience in elementary school, I would say that it was essential for me that my parents learned with me and helped me with my homework.
