There is no way "school" can equalise this.

There is, but it involves identifying the high achievers and putting them on a different track. Without too much thought, this sounds great. Except in real life, you end up with kids who are late-bloomers stuck in the "average" track. Or poor kids who didn't learn to read until kindergarten stuck in the "remedial" track for life.

As a society (in the US), we haven't been willing or able to solve those problems. The closest we've come is offering a few "gifted" courses to those high achievers (or forcing parents to pay for a private education). But, at the primary school level, that's generally a few hours/week of extra instruction. And at the secondary school level, it's AP/IB courses, but we've pushed the "college for all" narrative so hard that those are now watered-down crap at a lot of schools.
