I don't really get the purpose of the Taxpayers Alliance and their new 'Green Tax' calculator. If one accepts that taxes have to be raised in some manner then surely taxing something which creates negative externalities is a good thing. Obviously I'd prefer it if government spending were much lower but I don't really see why Green taxes are any worse than income tax, National Insurance, Stamp Duty or VAT.
They have been used in part to raise taxes by stealth- so the government doesn't have to raise income tax- but the problem there is surely ever rising taxes not the form they take.
Update: Just to clarify, when I say "I don't really get the purpose of the Taxpayers Alliance and their new 'Green Tax' calculator" I didn't intend to say that I didn't get the purpose of the TPA, I was just referring to the Green Tax Calculator.
