Polly Toynbee has a new year's wish in the Guardian today. Amongst them this:

¬? Create a standing tax commission to expose who pays what and how fat cats squeeze through loopholes. Get tough on tax exiles: cut the time they can spend here tax-free while stashing their cash in Jersey or Monaco, losing the Treasury escalating sums as the UK turns tax haven itself. Bring a top tax band at £100,000 as an opportunity tax, earmarked to pay for new life chances for left-behind children.

Spot on, I say.
