In a way, it does all boil down to the level of 'You say tomato and I say tomayto'. With no solid evidence that we'd be better off financially, politically, socially or culturally either way, it really is just a matter of preference. Do you call yourself British or Scottish or both?
At the moment I'd say life is better for the ordinary Scots because we have fewer people, fewer cuts to the NHS, Social Services and Education, no tuition fees, free care for the elderly, more mountains, better air - but as soon as you vote in a Socialist Government south of the border, you can have all that too ...
And the serious point that the young man was making in the video was spot on, imo.
