Gent wonders why the UK isn't doing what Norway did with putting energy profits into a sovereign wealth fund. Who's going to tell him that we've nearly exhausted all of the oil and gas in the North Sea, and that politicians preferred to extract profits rather than invest them for our national security. That is the real failure: politicians treated a finite national resource like ordinary income. Now they point to the small amount left as a reason to keep drilling, when the lesson should be to invest what remains and build lasting wealth through clean energy, industry and infrastructure.
