Re: If they say yes...
Yep, lower corporation tax, while spending more on welfare, while funding free tuition fees, oh and while Alex Salmond is at it, set up a Sovereign Wealth fund as well as cutting Corporation tax. The Yes campaign IS bullshit from start to finish. They want to spend Scotland's money in 3 different ways at the same time, any 5 year old could do the Maths and tell you it doesn't add up.
Oh, and the cutting the of corporation tax will do absolutely nothing to attract businesses, unless Scotland is going to go toe to toe with Ireland and cut it below 12%. Why would a business set up in Scotland, when they can set up in Ireland at an even lower cost?
As for the cost of things being different, OF COURSE they will be, I am absolutely shocked that this is not obvious to most people. If Scotland becomes independent it's going to be like going from France to Germany and expecting the costs to be the same, of course there will be differences, and in a lot of cases the costs will be higher because Scotland purely by its geography is harder to ship to (in case noone's looked at a map Scotland has a hell of a lot of hills, lochs and valleys).
