POGS, your 'line of questionning' is very aggressive- and I truly do not have to answer. I am still waiting patiently for questions I've asked of many months, even years ago. But still.
As said, things have got all mixed up on this thread- the rights and wrongs of private education- and the disproportionate power still held by the 'Old Boys Network' of Public Schools.
My comments re teachers who choose to teach in private schools, or leave the state system to go and teach in private schools- is due to personal, but anectodal evidence in my 30+ years of teaching in state schools. Two of my very good friends, sadly one no longer with us now, were excellent teachers, but could not cope with classes of 30+ mixed classes- I never blamed them- and our friendship endured. Some teachers are not 'bad' teachers, but cannot cope with the reality of state education as it is in the UK at the moment. Another who left, and perhaps the worst case, was a very poor teacher who was unable to speak either French and German he taught- but got excellent results. my Head of Department- so I was really surprised how he got such results. He was found out by the Advisors- as he hid in toilets everytime they came to assess him in his lessons- and then when he, as Examiner of one of the exam board- gave worksheets 2 weeks before the exams to include all the vocab and points of grammar, etc, contained in the exam. One of the students was surprised when every single bit turned up in the exam and told her parents, who were senior teachers elsewhere. He was quietly booted out, and went straight to a Private School across the county. Many of the Teacher training I supervised and who had real discipline problems, went straight into the private system after their first year- because they would not have 'survived' in the state system. But I agree, that didn't make them necessarily 'bad' teachers.
Where do I stand on Public Schools? I think that they do give a very unfair advantage, and that they do have a disproportionate influence in Politics and many parts of the commercial sector, especially banking and finance, and even more so in the City. Many I know very well. Jealous, no- I wouldn't want to work and do what they do, at all. But the tax tricks and evasion, and the lack of concern for others who are not so fortunate, does hurt.
Champagne socialists hey? Well, our kids never went to private schools, let alone Public Schools. It was a clear choice. So don't point the finger at us. But I did have this conversation with teaching friends in Senior posts in State schools who sent their kids to private schools. Their stance was that they were prepared to spend their whole life working their guts out to help provide the best education possible in the state sector, for all kids - but that in the present climate of cuts and underfunding - they realised it was not really possible. They could have chosen to teach in private schools, but were totally dedicated to the state sector, for all, where they had to work much much harder. But at the end of the day- they did not want to sacrifice their kids to their principles. I respected and understood that. As for Champagne socialists- let's say, like Benn- would you have more respect for them if they said 'let's drink champagne and s*d the rest- who cares? Or say 'we know and acknowledge that we have been very very privileged and lucky - so we will do everything we can to change the system'. I know which I'll respect personally.
Not easy to reply to angry questionning like yours - because the next thing is, you will point and say 'ah, virtue signalling' - can't win.
Last but not least. One thing which is well understood by Northern countries, and to some extent, the one where I was educated- is that choices don't live in a vacuum. When people choose to send kids to the Private sector, or when people choose to use Private Health Care- it does have a knock-on effect on the state sector in 100s of ways.
Perhaps better illustrated with the Private Health sector- where most Consultants work for both the NHS and the Private Sector - and the mix becomes truly unbalanced and squewed (sp?). 'sorry Madam, you will have to wait 6 months to a year to have your hip done' - 'oh I can't wait, maybe I can sell my house and take out all my savings to have it done privately?' - 'fine, will do the pre-op on Monday and book you in for Tuesday'.
