I can totally understand the need for Scotland to be able to set its own economic policy. But total independence would leave them materially poorer, and the UK destitute in every other way. The Scots, with the notable of exception of a 'certain' former Prime Minister impersonator, are brick and mortar to the nation. They've been our writers, our engineers, our economists, our soldiers.
Any talk about ancient wrongs is just the blether of mountebanks and carpetbaggers. If they decide to split then they'll be cutting off their nose to spite their face.
Worse, they'll be trading a nation in which they have a very great democratic voice for a super-state where they have none.
