I wouldn’t want any individual child’s education disrupted, so I hope they bring the tax in gradually and schools help existing pupils with bursaries etc. However, I don’t think the tax is unfair.
I do think a lot of high earners (I mean people families on £200k plus around) who exist in a little bubble of private schools, gyms, cleaners, at least one meal out per week don’t seem to understand any issues others may have with their ‘success’.
They don’t realise that they are disciples or Ayn Rand, Alan Greenspan and Thatcher, whose ideas have been somewhat discredited over the last 40 years or so. Our GINI coefficient is one of the highest in the world and we live in close-to crony capitalism where who you are born to, the school you went to and who you know is far more important than genuine talent (look at the idiot consultants and financiers on 7 figure salaries).
Private schools (with honourable exceptions like Westminster, who do a lot of community work) have really embraced the separation of society into the haves (have a world class theatre, have professional musicians supplementing school concerts, have a climbing wall etc) and have nots.
Societies always flip flop from more individualistic to more egalitarian. We seem to have reached peak individualistic. Those who are lucky enough to have benefited should at least do some reading and be cognisant that, if they live purely for self actualisation (including their children), resentment comes with the territory.
