I have followed the Scottish independence debate a bit, and a few things stand out.
The English seem to want union for two main reasons: to benefit from Scottish oil money, and to maintain their British identity and what little grandeur is left after their empire crumbled.
The English attitude seems patronizing, and their arguments intentionally fear based. Both suggest that they don’t have many real or solid arguments in their favor.
If the situation was the reverse – if Scotland was independent and considered union with England – how many would vote for union? Probably not many.
The yes and no sides are about equal right now. I assume many will vote “no” to independence out of a (understandable, if misguided) fear of change.
If they do vote “yes” to independence, the process will happen gradually and over time. It won’t happen overnight. There will be time to work out practical and good solutions.
If they vote “yes”, it will encourage others in Europe to seek independence, which is what England, Spain and others fear.
As of now, a few days before the vote, the two sides are about equal with a slight advantage to the “no” side. Unfortunately (?), that means the “no” side will probably get the majority of votes since many will go for what they perceive as the “safe” choice, which is status quo.
