I have decided at a broad level that a Yes vote would be beneficial for Economic growth in the long term in this country.. Firstly I think we are creeping closer towards a US style federal state system (albeit more culturally diverse) the Lisbon treaty from what I know of it is a more higher profile push towards this type of union, previous moves such as single currency, freedom of labour movement, and linked interest rates just cement this view..It will read quiet easy in 20 years time, people are confused because of the uncertainty change sometimes brings..but I think when we look back in the future it will make perfect sense
