high earners should not be taxed more than anybody else
They aren't. They pay no tax on their first 11,500. Like everyone else. The same 20% on the next 33,500. The same 40% on the next 105k, and then the same 45% on anything over 150k.
You're right, it's a horrible little quirk of the rates / withdrawal of allowances. But no govt will seek to change it because 100k + earners don't garner much popular sympathy.

There's no discrimination involved.
