Not a chance. The reason we are seeing a move to private education for leaders is the comprehensive system which stifles such qualities and revels in mediocrity
It doesn't stifle them - teachers actively try to encourage them where they see it but with larger class sizes and the performance measurements mean the teachers are forced into spending a disproportionate amount of time with those less capable because it's all about % of passes.
The problem with comprehensive education is it trying to ape private education and wanting everyone to succeed at the same things they perceive as most important - maths, science etc. That doesn't suit everybody but they're forced into doing it, get bored and frustrated and some therefore become disruptive, hampering those that are most capable. It also puts those kids off learning for a lifetime. Imagine if the kid that was a maths whiz with two left feet was told to put down the calculus and get outside and kick a football around for two hours every other day - he'd soon lose any desire to go to school.
As I've said before this idea needs to be knocked on the head and those that have other interests or abilities, whether they be artistic, humanities, sporting or whatever, should be encouraged to focus on those to keep their confidence and interest. They can be useful, economically active, members of society in those areas as well while also leaving those that do excel at things like maths more freedom and time with teachers to fulfil their potential.
