Summary
Five years after Brexit, its promises of sovereignty, economic gains, and reduced migration remain unfulfilled. While Brexit offers regulatory flexibility, its overall impacts are largely negative.
The UK economy has suffered a £100bn annual output loss, with GDP 4% smaller than it would have been without Brexit.
Trade barriers have reduced exports, particularly to the EU, with small businesses and sectors like agriculture and fishing hit hardest.
Migration has surged to record levels, but net EU migration has turned negative.
Public dissatisfaction is high, with 59% believing Brexit has gone poorly.
You underestimate how fucked Hungary is.
The UK would need to dissolve, London would need to be sacked by the Scottish taking the whole British museum, have this event define politics for the next century. 40 years into this, it would need to lose a world war, with the Russian army raping and pillaging through the land. Then live under Russian occupation for another half a century.
England then would be close to Hungary, not quite there though.
