Admittedly, I don’t know much about Brexit, but from what I have been exposed to, it seems like a decisively economical and political impairment that made travel and business with the rest of Europe more difficult and costly. Since it is so highly criticized as a terrible move, why doesn’t the UK just rejoin the EU?
The pound was a part of it, but there was always the UK’s veto which Margaret Thatcher negotiated, which also made the entire “BUT SOVEREIGNTY!!” thing a nonsense - now the UK is under the EU’s thumb, while before it could prevent the EU from doing anything that wasn’t in the UK’s best interests.
Despite her being associated with Euroskeptics I suspect even Thatcher would have been a Remainer.
Also a rebate, as one of the top 3 economies we should have paid a lot more in than we were.
While that it is definitely true, her reasons would be that it is easier to control and weaken the EU from the inside than from the outside.
