Here I’m using widgets as a synonym for the kinds of heavy industries we used to have. Reopening a steel mill or a tin mine is not something you can do overnight.

People forget that a factory itself is a sophisticated machine and operating it is an advanced skill that relies heavily on experience. A car factory is considerably more complex than any of the cars it produces, for example. Or, we never had a fab in Wales, but it’s a similar analogy. And then there’s the logistics, the supply chain, again a massively complex thing that is often overlooked. Maybe the factory had hundreds of suppliers and subcontractors, they would all need to be rebooted too. It’s a fractal problem.
