Phizzy what about the 40+ years previous to that when North Sea oil propped up the UK economy?
The fact is Scotland needs to develop its economy whether it becomes independent or not. One industry is in decline, others will replace it. Judging Scotland's economy on one year of low oil price is like evaluating someone's income during a month when they left one job and haven't started another yet.
Scotland still has a lot of oil and gas and could finally begin an oil fund like Norway, especially if the price recovers. And as Scotland adapts to no oil, it can copy many successful small countries without oil such as Denmark. Scotland has great resources and potential including tourism, renewable energy, food and drink exports, pharmaceuticals, financial services, worldclass universities.
Unionists need to explain how relying on handouts from London constitutes a viable economic plan. It's stupid, it's lazy, and it's pretty naive to think English people will go for it.
