Is there no one you disagree with politically who is just popular instead of populist, knowledgeable and yet disagrees with you? If you can't think of any then I'd suggest the problem lies within you.

> as it is won't be great
Great is a geographical term. Just as British people remain european after leaving the EU, they (those on the island of Great Britain) would remain part of Great Britain.
But do continue to regale us all from up high with your superior knowledge about economies and such, knowing things like why Great Britain is named as it is, that's just a trifling fact for plebs.
As is pointed out in every single one of these threads, inflation in the UK is no different to inflation in the rest of Europe. Like elsewhere, it's created by money printing to pay for lockdowns and other COVID measures, along with embargoes against Russia.
It's really quite impressive how often this claim about inflation and Brexit comes up on HN, despite it being so easily disproven by looking at the numbers. It seems to happen on literally every single thread about the UK. The idea that Remainer-ism is a bastion of economic logic and common sense doesn't fit with the frequency with which bad economic claims in support of EU membership are made.
I don't think it's a British problem either. We've had populists dominating politics in quite a few countries in recent decades. France just had a close call where a neo fascist came close to winning the elections. The Austrians have actually gone there. My home country the Netherlands has had populists come close a couple of times as well. Italy just elected a populist. The issue is that the type of policies populists preach tend to not involve a whole lot of carefully considered long term planning. Big gestures that are supposedly popular and then all hell breaks loose when reality and fantasy meet.
Brexit sounded great to people with no clue about how economies work. Now they are dealing with inflation, lots of failing policies, and the notion that they might soon have to rename their country as it is won't be great or united anymore if Scotland and Northern Ireland cease to be a part of it. I don't think anyone voted for that in England. But it would be a direct consequence of what they did vote for.
