Economics aside, this policy was never about "taxing the rich". This is a common smokescreen that people use on MN.
The people that send their kids to Eton, Harrow etc will not be bothered by a 20% increase in fees. For them it is a rounding error. They will simply laugh at the lower earners and go about their business. This is business as usual for them.
This policy is based on the politics of envy, but it is more directed from the lower class to the aspirational middle class.
People like yourself basically. People who make sacrifices to send their kids to a school that gives them a better education (and improved life chances).
You see, you are doing what they cannot. Or more concretely, what they have chosen not to do (spending the money on other things) for their own children.
So now they are resentful (by their own actions) and not doing so well in life (cost of living) so they are now trying to bring you down to their level. It was the same with Brexit: they want to damage you because they are not doing well and you are aiming to be better than them.
Thats what it comes down to: you are aiming to be better than them and that makes them resentful.
