It's so weird how people in the UK blame their economic woes on renewables and not the fact that they sanctioned themselves against their main trading partners with Brexit.
Like, what were you expecting? Breaking out of the EU (a primarily economic union) results in economic problems. Import controls requires stopping incoming trucks (sorry, incoming lorries) and that requires building major truck stop to avoid backups, and it increases shipping costs on everything. You(r govt) didn't build the truck stops, didn't set up any sort of plan until after the import controls went into effect, and were somehow surprised that putting up a trade barrier resulted in less trade, and a resulting economic slowdown.
I'm not a fan of Brexit but it is what it is.
I doubt that you are really a fan of all things EU but I am with you on unity being important and I absolutely agree we fucked up that one. I'm pretty sure we mildly screwed our economy from day one of Brexit - simply by inviting mutual tariffs for a smaller entity and losing the unified border.
However: I'm old enough (55) to remember quite a lot of EU history. Do you recall or have been told about wine lakes and butter and grain mountains?
