I see Wendy's husband is arguing from the position that economically, Scotland is more than able to function as a prosperous independent country. It's inevitable, because that's the simple truth. There is no black hole, and no subsidy junkies. The case for the union will have to switch to something else.
What has happened in the past is that a large proportion of revenue which is identifiably Scottish has been labelled as generically "British", while revenues specific to England (principally the City of London) have been asserted to be English. This manipulation of the figures has allowed a false impression to be given of the balance of the relationship.
Unfortunately it has led to a very negative attitude on the part of some English people, principally Daily Fail readers, that the Scots are scroungers and that it is the English taxpayer who is paying for the benefits that Scots enjoy (no, we're paying for these out of our pocket money actually).
The unionists have been running a very delicate balance, trying to maintain the illusion of Scotland too poverty-stricken to go it alone, while actually fighing desperately to retain what is a very healthy revenue stream which is set to get healthier. Once the argument starts to go into detail, the first part of that will really have to be abandoned, which is what Ashcroft seems to be accepting.
I remember seeing a very strange BBC Money Programme in about 1992, about Scottish independence. It was subliminally biassed, including a mock-up newspaper about English residents fleeing for the border on independence day, but it did include some knowledgeable participants. One economic expert gave a clear and compelling explanation of exactly how Scotland was in the black and would remain so. The presenters just ignored it, and went on discussing the "negative financial implications of independence" as an article of faith not to be relinquished by exposure to mere facts. This attitude is going to have to change.
