Private schools won’t ‘go under’. Those that send their kids to private school are the wealthiest people in the world.
We did a few years private before a move and 80% of the parents were very wealthy. Eg drive top range cars, have several holidays abroad each year, lots of luxuries, buy watches that cost more than my car, cars that cost more than my house. Very Davy with money. Lots of investments and the means to make more money (e.g contacts, properties etc). They value their kids education so aren’t suddenly going to pull them out. They may need to make ‘cut backs’.
So some were doctors, lawyers etc that had good incomes but may be less ‘wealth’ and it might impact them more. Again, however, they don’t need to drive a fancy car, they don’t need to have holidays, they don’t need to buy the most expensive brands etc. Most could find the savings easily. Most would have investments or family that could help. Very few that I knew would be completely priced out. The vast majority could find the money.
The schools also have a choice as to whether to pay the VAT from profit or pass the cost on to parents. Like all businesses they will do what helps them to survive and thrive.
I think if anyone votes purely to avoid this policy then it’s bonkers. Social inequality is bad for everyone - even those who have the most.
Of course parents aren’t going to want to pay more. But no VAT is unfair. It is a luxury when there is state provision.
