Don't worry we're used to it by now
Depends what you mean. Like pretty much every country it would run at a deficit and would be reliant on someone lending them money.
The media stories of 'scrounging subsidy junkies in Scotland' are generally fabrications based on a particular reading of the data when, in fact, all things considered the reality for some time was that Scotland contributed more to the Uk than they received back.
In 2016 I think that's probably no longer the case because the oil price has tanked.
My concern is that Scotland is possibly about to repeat the same mistake England just did in voting on one issue based on another. If people in Scotland want to be independent then great, lets do it. If people in Scotland vote for independence because they are upset about the EU decision and want to kick England that's just piling more stupidity on the heap.
One hope perhaps is that the UK will be so busy with the EU question that we might be able to have a discussion about independence here without so much Westminster interference and downright lies from the media and establishment in London.
I'd love to see some real honest fact based discussion for a change on what is a very important decision. Won't hold my breath though.
