"I agree with a lot that DAL says (though not the bits about whose contribution to society matters)... But at the same time, I just can't see myself, if my own dd went off the rails, blaming somebody else who "failed her"
Your DD is able to feed her own interests in her particular subject of strength. Some gifted kids can't, they need the help. Not all of them but some, definitely. Teachers can fail them. And do. Some may recover and take control. Some don't. And we as a society lose from those "don'ts"
I won't answer questions about my own IQ or income except to say I am satisfied with both - I left school at 16, returned to education as a mature student, earn well enough now, pay all my taxes in the UK and have no offshore accounts.
"DadAtLarge, is it not true that the top earners (100k + I magine you mean) within our country are also the best at dodging paying tax at all?"
Trust me, they're not. They may try to convert income to capital gains or do some other trivial tampering. But a large majority of them have no way out of the huge VAT returns every quarter, the increasing Business Rates, the extremely high National Insurance (12.8% employers' contributions) the Congestion Charge for their vans, Corporation Tax and a million other taxes. It's very few who go offshore and that avenue is being actively curtailed.
"an msc fits me for my next 15buck (£8) an hour job behind the counter at a bank in the back of beyond... after all, i could be doing great things and changing the course of humanity."
You've got the M.Sc so you've got the option. That's what I'd like gifted children to have - helped to reach their potential academically and then being, like you, in a position to choose space exploration or the seafood counter. I don't see what PMT has to do with the price of fish.
"Supermarkets are full of employees who have degrees and high IQs. I never understood the snobbery surrounding 'only' working in a shop/pub/bank etc"
It's not snobbery, it's common sense. While every shop assistant is doing a valuable job they are just not contributing as much to society (financially / non financially) as those who conceived the iPhone, invented a wonder prosthetic limb or founded Google.
And the practical result of me doing what I do and not working at a checkout is that I make a larger financial contribution to support those in society who need it. Would I rather there were more people in my position? Yes. Is that wrong? No. Treat the gifted like the DCSF demands and there'll be more future citizens in a position to choose to clean floors or aim higher (and we all stand to gain from their creativity, talent and money).
