The other aspect you’ve failed to notice is that many companies are eschewing offices now. They’ve proven they can work without them; Docker, for example, is now going fully remote.

To be honest, the above comment is exactly why Brexit happened: a refusal to see the bleeding obvious while chest-thumping and saying “we are the greatest”.

It’s why trade is basically avoiding the UK and new sea routes have opened up between Ireland And Europe — because the UK has made trade inefficient. No amount of chest thumping is going to change that dynamic, and England will be poorer because of it.

Reality doesn’t care about Brexit ideology.
