Many people (myself included) believe it wont hurt us badly, quite the opposite in fact. You and many others believe it will hurt us badly.
None of us has a crysral ball, so we shall just have to wait and see.
At least we are about to become a self governing, independent, democratic nation once again. Is there ever a bad time to to revert to that ?
Unfortunately, despite a period of promising growth, our economy had not recovered from the combo of the old eyed Scottish idiot and the global recession.
Europe is our biggest trading partner, and nobody beyond the God Farage sheep genuinely believes we will get free access to that. Which isn't ideal when we're not in a particularly strong financial position.
Maybe not, but we are in a much stronger financial position than every other EU country except Germany, and once the Euro currency collapses, Germany is up shit creek without a paddle.
We are though, in a very strong negotiating position with the EU, providing they don't send a team of faceless, chinless, spineless civil servants to do the negotiating.
