I work for a charity, and I had someone the other day refuse to allow Gift Aid on his donation (where the charity can reclaim the tax) because he said "the money I pay in tax is already being used for good causes". I'd never thought about it in those terms before, and I did give me a fresh perspective.
I don't think our tax system is necessarily fair (pensioners council tax bills for example, 40% for everyone over £30,000, whether they're earning £31,000 or £310,000), but I would hate for the UK to have the feeling that they seem to have in the US that tax is there to be resented / avoided / abolished.
Actually, in the year I was at home when DD was small, I HATED not being able to tick the "I am a taxpayer" box on donation forms. It was like saying "I am a non-person" in some ways!!
Random wafflings there!
