There is a key difference here, Scotland is a net recepient of tax receipts from London wheras Brussels was a net recepient of tax receipts from the UK. We were propping up the EU, not the other way around like Scotland is being propped up by the UK.
The EU is also a protectionist minded bloc, impervious to the lesson learned by the British when we repealed the Corn Laws and shot to prosperity with free trade in the second half of the 19th century.
Yet in both cases the economic arguments are in favor of being part of the union.
That’s why the Leave argument in the current calendar year veered towards the emotional argument and away from any economic argument.
I’m confused - you say “The EU is also a protectionist minded bloc” and yet at the same time others say it is a globalist organization
