Thoughts? You want some deep analysis beyond "good"?

why would bank taxes be taxed higher than other corporate profits?

Someone's going to try and point out that banks will leave investment out of the UK . Which holds as much water as a chocolate teacup in the Sahara.

Banks will manage their profits so the bare minimum goes to the tax man as they always do.

They will do this through various schemes that are legal in the UK and largely not legal elsewhere.
