We do trade freely with plenty of other countries. The EU is being awkward because we put their noses properly out of joint by leaving, and they don't like it. To an expansionary regime like the EU, having some awkward upstart walk away and cut about 15% off their economic might is a pretty big slap in the face. After 50 years of being able to grow ever larger and ever more controlling and bossy, Brexit has come as a nasty shock to their system. They never seriously believed anyone could or would ever leave, Until we did.
They've got massive internal economic and political problems right across the bloc. The political elite's answer is a false show of "european unity" - which is demonstrably fake because the Germans have just done a dirty vaccine deal despite signing up to the "one EU" procurement shitshow that has now gone very wrong. For all the EU's bluff and bluster, we in the UK have seriously wrongfooted them and shown their monolithic bureaucratic machine to be inflexible and utterly incompetent. That glimpse into their inner workings won't be lost on either their own member states populations or the rest of the world.
You lost me when you starting referring to the "political elite" - I stopped reading then as to avoid any claims of wanting to 'Drain The Swamp'.
No matter how you frame it we have left and it's caused prices to rise, big time. And prices tend not to fall once they have gone up. We are entering a recession and wages won't be going up anytime soon - even if they do not by 10-20%.
Brexit has shafted us. They were told it would but wouldn't listen, the just lapped up the rhetoric and propaganda. And now we all have to pick up the pieces (and pay more money for our bikes).
