"The taxes haven't been avoided, or even evaded. They just haven't been paid." - Vetinari.
I'm not wholly sold on the idea of having favoured literary authors setting tax law, or indeed any other laws. After all, everyone has different favourite authors.
Anyone that thinks avoidance and evasion are the same thing should feel free to send the Chancellor a payment of about £2k to make up for their own "avoision" in using their tax free earnings allowance. Anyone who doesn't send payment fundamentally agrees with me when it comes to their own money.
So, hands up all those sending cheques? Yeah, me neither.
