As long as Scotland gets the oil and gas fields that are in its waters, it will be fine.
There was a paper written in the 70's about what would happen if Scotland got independence, the opinion was so shocking that it was classified top secret until it became public under the freedom of info.
It basically said allowing it then would remove most of England's wealth and would see Scotland having to subsidise England.
Personally, I independence as a bad thing, especially in the current economical climate.
The economic outlook is somewhat different in 2012 to 1970s, but Scotland is still 'in credit'.
The strength of the UK economy varies from country to country and from region to region. Excluding the effects of North Sea Oil and Gas, England has the highest Gross value added (GVA) with Scotland close behind, though Scotland has a higher figure, estimated as approximately £24 000 per capita in 2009, once a geographical share of oil and gas is assigned
Also Scotland had the best rate of per capita growth (well actually smallest decline !) over the preceding 12 months, declining by 1.4%, ahead of the best performing region of England which was the North West with a decline of 1.9%. GVA per capita figures in GBP £ for 2009 for the four countries of the United Kingdom (excluding oil and gas) are:
1 England £ 20 442
2 Scotland £ 19 744
3 N. Ireland £ 15 795
4 Wales £ 14 842
Within England, GVA per capita is highest in London. The following table shows the GVA (2009) per capita of the 9 statistical regions of England. At the same time as Scotland getting independence, how about London &SE doing the same ?
1 Greater London £ 34,200
2 South East £ 20,923
3 East of England £ 18,591
4 South West £ 18,211
5 East Midlands £ 17,349
6 North West £ 17,263
7 West Midlands £ 16,788
8 Yorkshire-Humber£ 16,569
9 North East £ 15,621
Also two of the richest 10 areas in the European Union are in the United Kingdom. Inner London is number 1 with a GDP per capita of €65 138, and Berkshire, Buckinghamshire and Oxfordshire is number 7 with a GDP per capita of €37 379.
At the other end of the scale, Cornwall has the lowest GVA per head of any county or unitary authority in England, and it has received EU Convergence funding (formerly Objective One funding) since 2000.
