I caught up with an (ex) pro-Europe / anti-Brexit mate recently. He was saying Brexit has been a net positive overall with reference to the economy, Russia/Ukraine & the vaccine rollout etc. He says he felt lied to by Remainers who basically said the sky would fall in the day we left the EU.
I thought this was a fairly surprising position to take, but illustrates how reasonable people can reach different perspectives on complex & nebulous things. I should point out this guy is a phD and a senior exec in oil & gas who has previously lived and worked in France. So not an idiot.
I think brexit so far has probably been a negative all things considered. I’d estimate it has cost the UK something like 0.2% of GDP a year since 2016 and I’d put roughly a 70% level of confidence on it.
