I'm not agreeing with everything that this user wrote but for sure the Brexit did not destroy UK's economy. GDP-wise the UK and France always developed very similarly before Brexit and also after Brexit, so it's hard to call it a "desaster".
I still remember the articles saying that Britons will have no food on shelves after Brexit.
And no flights to Europe !! Since then, both Ryanair and Easyjet have OPENED new flights.between the UK and mainland Europe...
