Could be a fact that any effects of staying or leaving have been grossly exaggerated and in reality, it won't make a jot of difference to normal folk.
It's funny you say this as this is kind of my thinking right now. I'm torn between which way to vote but I think either way the UK will manage just fine even after the initial shock of leaving.
I personally think it's almost impossible to know how an out vote would pan out in the long term so at the end of the day people will be voting on principle rather than any sort of calculated figures or facts. I suspect areas such as the impact of EU law on UK sovereignty, a feeling of belonging to the EU (or not) as well as the immigration argument (unfortunately) may well well be big deciders here if it was to swing to an out vote as opposed to essentially guessing the long term economics.
