I've been wondering about this for a while. I know that in reality it would be impossible.......but.....I know very few privately educated adults who can afford to send their children privately. I'm also conscious that many parents send their DC for reasons other than wanting to ensure that their DC earn 6 figures when they grow up. Its all very well private schools publishing leaver university destinations, but if you go to oxbridge and then do a second degree that pays £25k/year you aren't going to be sending your own children to your old school. For the purposes of not drip feeding our DC are at private schools, and got moved from the state system because they were deeply unhappy. Im not convinced they'll end up with any better exam results but at least they'll have happy memories. But would I send them to a private school where the average alumni salary by mid 40's was £25k? Probably not.
