anniebach It really is quite insulting to say that anyone who criticises a system that entrenches and perpetuates unequal access to higher education and high office has a "chip on their shoulder". It suggests that such views are not genuinely held but only reflect personal resentment and envy.
A couple or so years ago you too refuted the accusation that those (such as yourself at that time) who criticised the wealth of the royal family had a personal axe to grind. It seems that you expect your concerns to be treated as altruistic, whereas others who express similar concerns are merely envious.
I have seen at first hand how students from universities outside of Oxbridge and St Andrews are viewed in a large city law firm. A partner for whom I worked disdainfully, and without embarassment, told me he rejected all trainee solicitor applicants unless they had attended such universities. Yet he, with his supposedly superior Oxbridge education, was the person who was partially, if not wholly, responsible for a major crisis in the firm which cost hundreds of thousands of people, including all the partners and employees in our firm, a significant depreciation in their pension funds.
