"Completely Rubbish Approximation to the truth"

"as I have argued many times, the accounting is biased and theoretically utterly flawed. When accounting it is vital that all estimates are prepared consistently and on the same basis. GERS has not been. Income is estimated on the basis of that arising IN Scotland but spending is estimated on the basis of that arising FOR Scotland. So, only taxes paid in Scotland are included. But expenditure in England (mainly), Wales and Northern Ireland is also charged to Scotland when Scotland is deemed to benefit from it. But the tax paid to generate that expenditure is not taken into account. The system is, then, inherently designed to show a deficit."
