@hillaryswankfan I’m not sure I understand what you are trying to say in your last post.
You are saying that parents with DC at independent school have bought a privilege - presumably you mean by this a better educational environment, more support, better facilities and less disruption. So a child with 3 A’s from that school has had to work less hard than a child at a state school - and definitely less hard than a child at a more challenging state school to achieve the same result.
Having achieved that result you’re saying that more of those children go on to university than the equivalent proportion of children from the state sector who achieved the same result. I’m assuming that the data showing that independently schooled children are over represented at unis shows that this is reflected even if you filter the intake so that you only look at those with a parity of results. (Incidentally are there any studies looking at the number of selective schools (so grammar schools, partially selective schools, faith schools etc) compared to those schools who do not select - to see if similar trends of over representation apply)?
but then you say that even when people leave university, with the same degree - which on the basis of the prior arguments, the state school educated child has worked harder for/is brighter as the independently educated child has had their privilege handed to them on a plate, within two years employers who employed what was to that two parable candidates are paying the independently educated ones more.
since a lot of jobs (unless vocational) have little to do with degrees and a levels, one has to wonder then why are those employers are doing that? They will be doing it for the good of their business - after all they want their business to succeed. Are they inherently biased so as doing this to the detriment of their business (and will any inherent bias be helped by reducing the number of independently educated pupils for them to be less able to be biased).
Or is it that an independent education provides rounder soft skills that they value and see as beneficial to the business.
If it’s the latter, the better course of action would be to focus on giving all pupils those skills. Taking them away from the independent school pupils by making it harder to obtain an independent education won’t give those skills to others.
