I can't believe the amount of rubbish and bigotry being spouted by both sides of the argument on this thread.
A private education does not turn a child into a super intelligent,snobby, brat who is guaranteed a high flying job in the city and anyone who presumes that is a fool, old school network or not.
Going to a comp does not Necessarily make them a thick chav, or stunt an otherwise intelligent, but "got in with the wrong crowd" or "wasn't given the opportunities because they didn't have the contacts".
There are successes and failures in both groups and one example doesn't prove the rule. Having had 3 children go through state, state/ private, private education respectively, I have been in every situation.
Most people do not have the option of private, lots would not want it anyway, either because state education is sufficiently good, political beliefs, or because of extreme examples of snobbery on here. Equally those with children in failing schools but have no option of doing anything about it are probably horrified at the suggestion that they should just go out and earn more money because it really isn't that easy.
Having contacts, works in all walks of life, whether old boys network or Dads mate down the pub, it is not the exclusive domain of the privately educated, just that there are extreme examples being bandied about.
And anyone else who sneers at the "rich but thick" element (and here, strangely the worst offenders are those on the private side) why should my average child, who wouldn't pass 11+ in a million years, not be in private education? Will it make her intelligent? No. Are we wasting our money? No. She is in a nice environment, in a class of 11, she is happy. She is not a brat. Is it culturally diverse? Yes. There is a huge mix of wealthy/ middle class/ working class and she attends clubs with some of the most deprived children in our area, so gets a proper mix of privilege and real world.
If you are lucky enough to have choices, you make them accordingly. You do your best for your child, at that time. We have been able to make choices with 2 of our DC, we did not have that luxury with our first, much older, DC and state education failed him. When your only option is a failing comp, that gets locked down because of gang warfare between rival schools, drug culture and knife crime, it is totally demoralising. He has though, come through it a nice, well mannered boy who is doing very well for himself. No one could convince me that I have not made the right decision to not allow my other DC to experience that though, just because for them, I had the option to do something about it.
Rant over. Flame away.
