The argument that Scotland must stay in the union to receive handouts from London is bizarre on all sorts of levels.
It ignores that Scotland has been a net contributor to the UK for decades because of oil revenue.
If you say that's all history now, and oil is over, fair enough. But the theory that London will hand out money to Scotland indefinitely has not been tested. It presumes firstly that Scotland will not make up for oil revenue with other sources of income, and secondly it assumes that if Scotland fails to increase its revenue that London will send us money to make up the difference indefinitely.
Given that many in the rest of the UK seem to be under the impression that Scotland has been subsidised for decades, despite money actually flowing in the other direction since the 1970s, how likely is it they are going to actually to send a net contribution to Scotland indefinitely?
Even if you grant all these assumptions:
1. That Scottish oil revenue won't revive
2. That Scotland won't be able to grow other industries to take its place
3. That we need money from London to survive
4. That London won't cut off the money at some point
Even if you grant all those dubious assumptions, what sort of self-respecting people really thinks the only viable future they can have in the world is to reply on handouts from someone else? That other small countries such as Denmark and Switzerland are prosperous without oil, but the idea that Scots could do the same is complete fantasy?
There is no doubt that Scotland's economy faces significant challenges as the oil industry declines. What is not clear is how unionism offers any sort of solution to this problem. In fact it is worse that that, it implies we don't need to find a solution, we don't need to fix our economy, or grow other industries. All we need to do is rely on the generosity of London and them to send us money indefinitely.
That's unrealistic an offers no real solution.
