correction

revenue before=

is supposed to be revenue becomes (ie after inflation)

a type on darn phone

and also remmber, i made this simple and assumed in case A you are not paying any tax at all

but the same logic still works if you set up an example where you were paying taxes in the first place, you will just go on to pay more taxes in real terms

so insted of taxes being

0+more
you have

original+more....
