Well, no, actually, as the IFS the Tory think tank pointed out, it doesn't. Scotland would be broke after a few weeks, because you are too wee, too poor, and far too stupid.
We were lying and being patronising, because both of these things are what we do best.
Well, except in the case of Cameron (who does a splendid impression of Flashman), it's more or less the only two things we do.
Still, at the end of the day we'll all be sitting in the House of Peers on £300+ tax free a day, with lovely money earning titles, so why would we actually give a toss?
