I am not sure you’d take my word for it but if you can please read this article in the Guardian from last year.
It sums up the SNP’s arrogance and naivety to a tie IMO, with their response:
I’ll read it if you read this. From Business for Scotland.
In the 1970s, Scottish oil revenues stopped the UK from going bust and requiring a bailout, but they were not enough to stop the UK debt mountain from growing. Scotland was then allocated a population percentage share of the costs of servicing that debt as well. Despite this double bailout of the UK, Scotland’s economy and its finances still managed to show a higher GDP per head and lower illustrative deficits than the UK until 2015. At that point, the UK’s mishandling of Scotland’s oil and gas wealth caught up with it and it decided to slash Scotland’s oil revenues by reducing the tax on oil extraction, which finally made Scotland’s finances look worse than the rest of the UK’s.
But it’s the UK’s deficit, not Scotland’s. If an independent Scotland had done the daftest thing it could have done with its historical surpluses, then as a nation, Scotland would be £508bn richer than GERS suggests it is, as part of the UK. If it had simply copied Norway, Scotland would have £547.5bn in a Scottish wealth fund right now.
It’s fair to say that in 2014 many people just didn’t believe Business for Scotland when we explained that Westminster was completely economically incompetent, that Westminster truly didn’t care about the impact of its policies on Scotland and was deliberately acting against Scotland’s best interests.
Now, however, Brexit is making that thinking mainstream, and slowly but surely, as Brexit unravels, more and more people are beginning to see that Scotland cannot afford to continue subsidising this failing, disinterested and dysfunctional Union. The UK economy is in a fragile state and has not yet recovered from the 2007 financial crash, despite more than a decade of austerity and real terms cuts to public spending on essential services.
The evidence is clear. The UK Government has created a situation where Scotland’s finances show a false deficit, one that is not related to the economic performance of Scotland. Pro-Union politicians and the highly biased mainstream media point to that false deficit and say that it is proof that Scotland can’t afford independence.
This will continue until the SNP Government becomes more assertive, and gets better at explaining that what GERS actually proves, emphatically, is that Scotland’s economy is remarkably resilient and resistant to oil price fluctuations, that it is under-performing due to carrying the weight of generations of Westminster debt, economic incompetence and wrong-headed thinking on its back.
