Sigh, well history again, Scotland was the biggest single investor in the Darien Schemes in the 17th Century, some believed as much as four fifths of the entire wealth of the Country was lost so much so that Scotland was basically bankrupt with huge debts and the only way out of this disaster was to "sell the Country" which was in fact achieved with the act of Union.
There have certainly been times where Scots could argue that they have been exploited, the Industrial revolution through to the twentieth Century and the development of Oil and Gas but this is a biased view as a) the debts were written down as part of the Union and b) the oil and gas reserves were discovered and developed by the state as a Union
Scotland is a small country economically and with a very small population, it shows the fortitude of its educated people that as part of the Union it is able to "punch well above it's weight" within it, and command respect on a Worldwide scale. I would be concerned for the people in taking a step into Independence with no real long term surety of fiscal stability!
I have told any Scot who would listen to vote SNP to get a better deal and that has proven to work, devolution has been good for Scotland in my humble opinion and keeping Westminster aware of the power of a people is a good thing! But I do not feel it would benefit anyone for Independence to go ahead, (not a chance anyway from what I hear!).
The statements of costing England are not strictly true, over 26 years the balance between support and revenue have balanced about equal, albeit a lot of services are not included, but there is some need to support a people who certainly supported us in the manufacturing and export days of our Union quite dramatically! (I have heard that the last foundry in Falkirk has closed, please tell me it isn't so! )
As British I don't want us to lose Scotland from the Union, it is the Union that makes us all better off and I do care what happens to Scotland. It simply wont happen anyway --- I am afraid that Alex Sammond will have to look to be King of somewhere else!
