This one is a toughie.
For Scotland and people living there, IMO Scots should vote YES to independence. ("No tory government for scotland ever again")
But for England and the people living there, the Scots should vote NO or we are stuck with the tories forever.
Scotland can do fine without the rest of the UK.
On the issue of monetary policy, its pretty simple. Either they are allowed to keep the £ and get a share of the debt or they aren't in which case Rest of the UK keeps the pound and the debt.
Scotland will do fine as an oil economy. It has enough natural resources to not need nuclear.
It has no enemies nearby so it doesnt even really need armed forces apart from for the sake of pride abd future deterrence in the case the vikings invade.
It also wants more immigration so it can have its own immigration policy to attract more people to it, while England can go down its own route (which incidentally is a bad thing - immigration = good.)
