This is a very simplistic question but, whilst I accept that your intentions are good and fair for the education system, can you tell me how an education system which allows parents to 'buy' results(and thus places at 'top' universities etc etc) by using the private sector can ever be seen as fair??
For the vast majority of parents (not me personally I may add), scrimping and saving, not having foreign holidays/flat screen tv/drinking/smoking (all the usual suspects) will NOT enable them to pay for a private education and all the advantages that such an education will (wrongly, in my opinion) confer on them.
(Disclaimer I have two older children at top universities and one younger at top state grammar school so have no personal axe to grind)
Also, if one has a voucher scheme, I may be hugely missing the point here, but what happens if everyone wants to go to one school and no-one wants to go to another, as will so surely happen (i.e everyone wanting to go to the nice middle class 'best' school and no-one wants to go to the one with undesirables 'second best').
I do quite like your idea of going back to traditional learning systems though and please could you STOP the dumbing down of exams (as, e.g, my son managed to get an A in Physics which is a bit of a joke really). Make them all harder then only the truly really bright will get the top grades, and it will also have the added effect of stopping those averagely bright children at private schools coming out with strings of As who are no brighter than those at the local comp who don't come out with the same grades. The private sector has got the current exam system down to a tee, and I absolutely refuse to believe that a child whose parent's can pay is somehow naturally more intelligent than those whose parents can't afford to pay (i.e the VAST majority of normal, working people). I am sure you would agree with me as you seem quite a nice chap
