That's the pointless debate though for those who always have economic issues on their minds. Armageddon, disaster, bad, worse. I had pretty much zero interest in the economics before or after the vote beyond saying those claiming armageddon were being silly. And they were.
Im not sure trying to argue the effects economically does any good whatsoever but a decade later its still happening daily. Its pretty odd.
Personally I would say covid, austerity and the Ukraine war are the biggest reason for our decline. I also have a nagging feeling Europe has had its day.
Leaving wouldn't have happened if the oh so clever folk had been.... well a bit more clever.
Anyhow its happened and our malaise will continue because we are devoid of any actual new ideas.
I would vote the same way tomorrow, no hesitation.
