I don’t really understand your point. All of these kids until 16 went to school private or state (not sure what the relevance is to pointing this out).
At this stage, academy kids don’t go to college or continue with a levels. They effectively do an apprenticeship and do the equivalent of three a levels - in fact one of the boys currently at the cat 1 academy my son is at is doing an economics degree at LSE. My son is doing two additional a levels funded by the club. The ckub have agreed to fund his uni if he continues at the club.
So yeah they are educated. They can go on academically. Academics are considered important. And private had nothing to do with it.
I have been to both and private wasn’t better and isn’t relevant to being educated while at an academy.
