What's wrong with having an educated government? I'd rather have some intelligent "public schoolboys" in government, rather than, for example, having a home secretary who was going to pay 10,000 extra police officers £30 per year, each.
In any case, 59% of Conservative MP's were educated at comprehensive schools, rather than private schools. With each year that passes, that figure is increasingly becoming more representative of the general population. Conservatives MP's are also more likely to have real world experience, i.e. in finance and general business. Real world experience is just as valuable as whatever may be taught in ones younger years.
Maybe this is why the Tories have an 80 seat majority?
