All we can really do at this point is look at the general direction in which we’d like to travel, either a more unequal society (by any independent measure) or somewhere that cares a bit more about the less advantaged.
I think it’s even more fundamental than that: Simply, do we want to be free to decide for ourselves?
Scotland hasn’t mattered in the UK for a long time – the way we vote doesn’t matter, our opinions don’t matter, nothing we can do will change the situation – apart from this. We can decide to be able to decide things for ourselves.
I hope Scotland will be a better place after independence, but that doesn’t affect my decision.
