A sage said 'nothing can be certain but death and taxes'. In fact the 'who pays' question is obscured and avoided by politicians and public alike. Polly Toynbee and David Walker, authors of Cameron's Coup and Unjust Rewards, argue that the biggest issue in modern politics is honesty: you can't have Swedish services on US tax rates. Whether it's Scotland, the UK, the case for fair taxation for decent public services is incontrovertible. Bankers and fat cats have to pay more but so does everyone else.
