What reasoning? You're just making some weird argument that an unnecessary luxury shouldn't be subject to VAT because most super rich people don't use it (no citation). I bought some cheap beer today that most super rich people probably don't buy. Should that also have been VAT-exempt?

Data from UCL study on PS family incomes. Education is a merit good like food (zero rated), medicine, dentistry, books. More of it benefits society. It’s daft to tax it and it still is exempt unless you are 5-18.
