Their whole thing was that Scottish independence was a good thing, but it wouldn't be possible (or even a good idea) because Scotland wouldn't be able to support their economy on their own. Does that response hold water?
As a disclaimer we are U.S. citizens, and I definitely don't know much about Scotland, so feel free to dump whatever information on me that you want
They are very deeply intigrated economies so that would either remain the case or there would be trouble but when they get austerity they'll do well under it because scots hate spending money
