So, we have to plan for massive insulation programmes. Large-scale solar installation is also necessary. Heat pumps need to be rolled out at the rate of more than 20,000 a week if we are to have any chance of reaching net zero commitments, and these could be made in the UK using skills now being declared redundant in many factories. And all this, of course, is just a start.
But this is not the only area where we need more employment.
We need more people in education: children who have lost out need support.
And the care sector is critically short of staff to meet need.
In addition, almost every aspect of the creative sector needs support.
That said, Labour will have to be discriminating: there are jobs that do not need preservation. The days of air travel may be numbered. We are over endowed with financial services. The world could survive without Uber and Deliveroo, because it did until recently, and these are not good jobs.
The world also survived without more care workers, more people in education, more support for the creative sector. But the argument that the world did survive without them is not used, is it? Only the things that are unfashionable get subjected to that retort.
And then there’s the conservatism of the base logic there too. If caves were good enough for grandpa then why worry about wattle and daub? Or even, why come down out of the trees at all?
