Without it, Thatcherism would have been impossible. No oil money, and the welfare bill for mass unemployment would have been unsustainable. Without that unemployment, union power couldn’t have been broken, and privatisation would have been far harder.

It was oil revenues that bankrolled the unemployment, the destruction of manufacturing, the high exchange rate, the termination of British coal mining, and the big bang that turned London into arguably THE capital of global neoliberalism.

Oil revenues were used to cut taxes for business and the wealthy and to fund benefits during a wave of industrial closures. The oil money paid for tax cuts at the top and the benefits at the bottom. Despite Thatcher’s reputation as a prudent manager of finance, no money was set aside for the future.

The government could afford a long confrontation with the miners because it had both the fiscal cushion and an alternative energy supply. Without North Sea gas, a miners' strike long enough to threaten power generation would have been genuinely dangerous to the government's survival.

And then, to complete the insanity, Thatcher privatised the industry generating the revenues that were funding the whole operation. The British National Oil Company (BNOC) was privatised in two phases in 1982 and 1985.

BNOC was created by Harold Wilson's government in 1975, specifically to give the British state a direct stake in North Sea extraction rather than leaving it entirely to private multinationals like BP and Shell. It was our equivalent of Norway's Statoil, established around the same time.

And of course the government freed itself in stages from all its equity in BP: 51% state ownership in 1977, down to 46% in 1981, 31.5% in 1983, and fully privatised in 1987.

Labour built the institutional architecture to capture public value from a public resource; Thatcher dismantled it, took a short-term cash payment, and handed the long-term revenue stream to private shareholders.

Norway kept its equivalent. And that is why Norway has the money to subsidise EVs to the point where it barely needs oil for cars, and we do not.
