Most people can't pay less tax. As
Leona Helmsley said: "We don't pay taxes. Only the little people pay taxes."
If
everybody could pay less tax, then society as we know it would collapse. Who would pay for the roads, hospitals, rubbish disposal, sewage maintenance, police force, research and development, military, education, etc. If people wish to pay no tax at all, I could point to some tinpot countries they could enjoy a 0% rate in.
That is what makes this stink. People like Gary Barlow were able to make their wealth thanks to everything our society offers, from the infrastructure to the wealth of an educated population. You don't see many multimillionaire pianists coming out of Darfur.
There is a social contract. You benefit and profit from society but pay a share back. People like Barlow are parasites. And he has the cheek to appeal for money from the rest of us for Children in Need, i.e. we are subsidising him.
