There aren't tariffs on trade between UK countries and in EU common market atm
Technically but that is part of what we pay into the EU for, and in fact originally it was mainly what we paid in for iirc. So it's untrue to say that we don't pay tariffs, we just pay an overall payment that effectively pays for the absence of tariffs.
Also, you need to fotget about independent membership of the Eu for Scotland and relying on what that can make up for. We aren't going to have that in any way near the short term, possibly not in my lifetime.
And No, Scotland doesn't have any of those things. I work in Financial Regulation, we would need a new level of regulation, it's really not simple.
yes, we have banks but those are commercial banks with their own independent agendas, not a central financial organisation that works for the overall country, not to make money themselves as such.
Having said that, if there was a decent case then sometimes it's worth being poorer in order to achieve a greater good, that decent case really doesn't exist. The vast majority of Scots are better off that they ever were. When you look around the world, there aren't many that have things as good as we have here, that's why people want to get here, who can blame them?
Yes, there are some really important issues that face this country, and more so in Scotland than in some other parts of the UK. Some of those have been caused by the SNP either by direct policies or by ineptitude. if NS and her cronies would just make some solid, decent effort to resolve those then I'd have a greater respect for them. It's good for them to keep people feeling poor and disgruntled while she is blaming Westminster for that. Some of it is indeed Westminsters fault, but a lot of it can be squarely laid at their own door.
Scotland has a lot of bright, talented, hard working people (same as everywhere). It also has a lot of people that think that money goes on trees and that the world owes them a living (same as everywhere). We are not so different as SNP likes to make out. We are not one homogenous group that all believes the same things and wants the same things. However at the moment the majority of the people in this country are being misrepresented by the SNP.
