We need to stop kidding ourselves that we can turn all children from all backgrounds into academics/professionals by throwing more money at them and moving the goalposts ever wider for university entrance. Surely the money would be better spent on concentrating on a decent level of competence in English and Maths for everyone, and giving them whatever intensive support is needed to achieve that. Then, let's identify, early, the children for whom academic success will always be a long shot.
We should be looking for their strengths and celebrating them, giving them support and encouragement in learning trades/vocations, and funding small businesses to set up old fashioned apprenticeship schemes to take school leavers and actually train them and nurture them, rather than use them as cheap labour. Businesses could afford to do this if the government funded the student with a grant or gave them an apprentice's loan, in the same way they do with student loans. They stand a better chance of social mobility by earning a good wage as a plumber or hairdresser, for example, than they do by being on the dole queue as a third class graduate in HipHop studies, or whatever.
That would be money well spent in my opinion.
Also we should sponser motivational mentors who are 'normal' and unintimidating, that working class kids can identify with, (similar background, similar ethnicity etc) to go into schools and home in on kids from disadvantaged backgrounds (while they are young enough to listen) who have been identified as being bright but directionless. They should be saying 'Look at me, I am a Teacher/Accountant/Area-Manager for Tesco, self-employed builder (or whatever.) I have a house, a nice car, and a happy family. I did it, and so can you, because you are as good as anybody, and I'll keep telling you and hounding you until you believe me!'
We should be looking to insirational people like Jamie Oliver who is dyslexic, and Duncan Bannatyne who came from nothing, to support initiatives in schools to show disadvantaged kids that with a strong work ethic and some ingenuity/guts you can achieve, if not great riches, then at least self sufficiency and a sense of pride in yourself.
We need to STOP IMMEDIATELY with enabling working class kids to labour under the delusion that a realistic career option is footballer/rapper/model/actress/street dancer. Of course they may make it, someone has to, but they need to see that it a very, very long shot, and that working for a living is not necessarily guaranteed to be an extension of their hobby, not even necessarily highly enjoyable or highly lucrative. And fame is not a human right! However, they have a responsibility to themselves to aim to be employable in something, and self-suffiency and employment will give them greater self-esteem and more choices than anything else else can. I think that's a big part of the problem - the fact that many of them have no sense responsibility for, or control over their own destinies. The benign welfare/nanny state has a lot to answer for there....
Lastly, (and I really am going to shut up in a minute!) we need some tough love and a return to (some)old-fashioned values. With those two things in place we should see fewer disadvantaged kids in schools in the first place. At the moment we enable people to perpetuate cycles of disadvantage, but that's another argument for another day. Sorry to sound like Tory polititian, but we do.
