"Without offices there is no trade for anyone else, including shops, pubs, cafes, restaurants, cleaning and maintenance companies … etc"
But that IS the point, surely. Most/many non-productive jobs are just not necessary. All they do is provide work for other non-productive jobs.
Prioritize. Important work: the production and distribution of food. The care for the sick, so doctors, nurses, and their immediate support staff (not hospital managers).
But much of the work the British now do is not important. It keeps the non-productive economy ticking over, but, like face-to-face hospital consultations, it really isn't necessary in most cases.
Step aside from your prejudices and LOOK.
