Which brings me back to my original thesis that everything is about as likely to fine whether run from London or [is Edinburgh the capital?] since they both have dumb politicians and mismanagement and so the economic question basically doesn't matter so let's go back to discussing different philosophies of identity formation and how they relate to theories of sovereignty.
Ok, we really need to qualify 'dumb' politicians. The Westminster bunch may seem dumb, but they certainly are not. Every politician looks dumb. That doesn't mean they are as dumb as each other. I think, for example, the SNP is dumber than Westminster as far as economics are concerned.
So, if Scotland stays in the UK, they'll have dumb politicians and no extra costs.
If they leave, they'll have dumber politicians, and lots of extra costs.
