Sure, the country didn't go back to be a developing nation, but "similar economic trajectories" leaves a lot of margin for how much better or worse it could have been. Purely economically, about 2-5% of GDP growth seems to have been left on the table, and in terms of human cost it's really hard to say anything positive about closing international borders between similar and allied countries

Every single one of the predictions of the Brexiters has been exploded: migration, taxation, funding the NHS, better public services etc.

The cost of implementing customs controls ALONE amounted to more than the sum total of UK contributions to the EU budget from day 1 of the UK joining the common market. The losses to the UK economy have been staggering -- up to 8% of GDP on a recurring basis. And no the UK didn't have a cold-turkey exit from the EU, that would have been a "no deal" exit.

But... but... splutter Brexiters, "look at Germany". Always looking at growth rates and cherrypicking data. Germany has had a massive increase in energy costs, far greater than experienced in the UK.

Go on: tell us Brexit is a mere "flesh wound"

Brexit has been a bone-crushing failure and repeated polls show a majority of the electorate knows it. A toxic minority of older voters, the UK's MAGA cohort, is ready to double down, and all they will achieve if they get anywhere near govt is the breakup of the UK, wihch of course many younger non-English voters support. Either way it's been a quite boon to the EU.
