I'm wading in when I don't know much, but surely it is incredibly short termist, and a misunderstanding of what the referendum is about, to vote yes due to a desire for a particular party or political approach, eg. left wing, less austere etc. This vote will not decide anything about what kind of policies will dominate over the years, could be right wing or left wing.
Also I fear austerity will be on the rise in the event of a yes vote. Scotland would really have to prove itself in terms of no defaulting on debts etc, and possibly adopt certain measures based on EU demands if they apply to join.
I don't understand why the best option if you don't like the way the NHS etc is going, is to leave the UK, rather than try to change or improve things as the UK.
DP is threatening to emigrate if yes is the result. He feels British rather than English and that the country will be destroyed. I don't know how I'll cheer him up if we get left. It feels like being left.
