living vicariously
£30-£35 billion would be a drop in the ocean for spending here. In this financial year government spending is expected to be over 1,200 billion (https://obr.uk/forecasts-in-depth/brief-guides-and-explainers/public-finances/)Not really. You just have to resist the temptation to spunk it all straight away.
Assume an equal ability to invest it wisely and limit spending from it to a sustainable level and we'd be in the same position as the Norwegians. The amount of oil and gas extracted by the UK and Norway is similar.
They now spend £30-35bn a year from it while the fund still grows.
We let the private sector take a big chunk and spaffed the rest on some tax cuts and immediate spending.
Norway's total expenditure was set at 1.88 trillion NOK which equates to approx 135 billion sterling approx 11% of UK.
So yes it is easier to accumulate a wealth fund when there is less to spend it on.
