I have confidence that kids from comprehensives can do anything, achieve anything, be doctors, engineers, etc. Those people denigrating comps and state school kids are not helping this argument one little bit. My kids will do well at state school, partly because we are privileged enough to help them and support them out of school hours.
Some other kids go to schools where the parents pay the fees. It costs loads - almost as much as my annual salary - but I don't mind, crack on. Those parents don't get to opt out of paying for the state school place they are entitled to, but they are opting out of using it. Which makes life better for my kids.
Making it unaffordable for many to continue in private school means they will come and take what's rightfully theirs, making school a little bit more squeezed for everyone else.
VAT might cancel out the cost issue but it won't magic up bigger classrooms or more teachers.
The only people this policy won't harm is the super rich, because they are super rich. There aren't very many of them either
