The answer lies with those cretins who voted in labour over a decade ago. How come anyone could believe "new labour" had changed!
That said, we are stuck with it and the horrendous consequences for a while, but whinging about the tax one pays is not going to achieve anything, and a system of the more you earn the more you pay is adopted everywhere in the world. Any other system would produce anarchy. (look at Thatcher's attempt to impose a fat rate poll tax)
If you really have had enuf then up sticks and leave, I think there would be enough qualified people who would want your job.
