In 2014, by about 2%, Scotland voted to remain in the UK. Those who voted against independence ("NO") obviously (it seems to me) did so on more than one factor. They reckon Scotland could not survive on its own, that Scotland is incapable, incompetent, and that it only survives through the generosity of England - I have heard this stated more or less word for word by university educated Scots. Any comparison with countries of similar population size or smaller, with fewer natural resources and less land than Scotland, is dismissed as irrelevant, could never apply to Scotland. These countries do far better inside and outside (mixed) the EU than the UK does, all comparisons consistently show this - yet the status quo is considered as good as it gets for Scotland. Hang onto what you have for the certainty, including the certainty that it will permanently be well below the best.
One of the reasons/factors put forward in the 2014 referendum was that Scotland would end up outside the EU if it left the UK. Now it is leaving anyway, all because it left its fate in the hands of the English (no UK election/referendum would ever go against an English majority, a numerical impossibility).
Still there are people who argue that for it to leave the UK would be a disaster for Scotland, lunacy. Should Scotland ever be so insane as to leave the UK then it will certainly beg to return within a winter or two. Meanwhile, the SNP is far and away the largest party in Scotland.
Somehow none of this adds up to a conclusion that a Scotland within the UK is a natural and logical inevitability or that that is necessarily the best for Scotland, or even England for that matter.
These things have yet to play out and we can but wait. Some of those making the most outrageous statements may not have long enough to live to see the outcome. Like quite a few, I know what I want to see happen, and it may not be that far off. For the record, on behalf of Scots, I find the premise that Scots are overwhelmingly useless in independently serving their own best interests - they may have been brought up to despair ("We're doomed, we're a' doomed") but I am convinced that, given the chance and need (necessity is the....), they would/will be able of significantly improving on the backwardness (not mentioning current political chaos/mess) that is the UK.
My biggest reservation is on whether they could arrange a radical enough change quickly enough to make the absolute best of things - after all, last time more than half of them clearly lacked the necessary vision.
