I think it would be pretty safe to say if not for English taxpayers bailing out the doooooomed RBS there would be no Scottish economy. The country would be bankrupt.
The EU, who some of the Scots, it would appear , are so happy to join were not exactly sympathetic to Scotland's plight either. Be careful what you wish for :-)
/Restructuring charges — have left the cost of shrinking the bank at £13bn, as RBS has sold businesses and slashed costs in an effort to stem losses. An estimated 90,000 jobs have gone from the business since 2008, when RBS had operations in 54 countries that spanned all areas of financing, from aircraft leasing to current accounts. As a penalty for the state aid required to keep the bank in business. the EU forced RBS to sell off businesses including commodity broker Sempra, the money transmission business WorldPay, insurer Direct Line and US bank Citizens. All these took thousands of staff with them. The EU also demanded RBS get rid of 300 UK branches. They were separated and RBS tried to sell them, but that effort has now been abandoned – at a cost of £2.5bn.//
