I'm really trying to understand your world view, since you clearly believe it passionately - and it's very different to how I understand the world.
Do you genuinely believe that:
a) private schools don't on average give a better education than state schools? (obviously there will always be outliers in both directions in each sectors)
AND
b) the only reason for the different outcomes for state and privately educated children is a free-mason type system where privately-educated people give additional opportunities to other privately-educated people? And this is given because of the schools they both attended? (Not talking about Eton, but an average private school: there are about 2600 in the UK, and you've probably heard of about 10).
Really?!?
What mechanism do you think exists to make that happen??
At least give me a plausible scenario where John A who went to 'Random-private-school-in-Oxfordshire' gets unfair advantages ahead of John B who went to 'Pleasant-Comp-Next-Door'?
...Assuming they are similarly academically able, no SN or ND, both came from very similar middle class families, secure homes, lots of books at home, bedtime stories, music and sports clubs, tutor/kumon if they were struggling. Slightly nicer holidays and a part-time working Mum for John B (John A's mum works full time to afford the fees), but still both had nice family time and have engaged parents.
Seriously - what mechanism does John A's advantage come from??
