I think that the majority of voters, really had no idea of the complexity and level of difficulty in extricating us from the EU, or were even considering the possible negative consequences. I've got my pension, I'm all right. maybe.
I don't think politicians knew either before the referendum, or do even yet.
Leaving is just the mirror image of joining though, I don't think the politicians who took us in had the first clue as to the complexity or difficulties of tryng to make our union to the continentals work, nor of the potential negative consequences. It was all 'don the rose tinted and crash right in'.
There was certainly a very bumpy road in the aftermath of joining for several years, until Thatcher did a 'Paul Daniels' to raise cash by somehow convincing a gullible public it was a brilliant scheme to sell back to them what they already owned. Prior to that it had been rampant inflation, the three day week, numerous and continual strikes, and successive short term unstable Labour governments leaving the country run more by a handful of loony lefty trade unionists than the elected representatives.
Yes, there's always going to be the old argument as to whether those troubled times would have happened anyway if we'd never joined, and the parallel one that it would have been much worse if we hadn't been in. Those can never be proven or disproven, as they're possible alternative histories which never happened, the only thing that cannot be disputed is that being in didn't prevent it happening.
Yeah, no doubt there will be bumps coming back out too, it would be naive to expect otherwise. The alternative though is to remain in an unholy union that has never worked very well, and has been working less well by the day now for the last decade or two, until the whole rotten sheebang implodes in on itself and leaves its members to crawl from the wreckage and have to try and do as best they can on their tod with whatever they're left with.
Personally I'd rather we bailed now in a planned and orderly manner and faced the inevitable issues that raises while we have time on our side and some resources left to do it, than have to try and drag ourselves up by the bootstraps after they've bled us dry yet again.
If anybody is making the bumps in the road ahead greater obstacles than they ever needed be, its the numpties in charge in Westminster, who have spent the last 18 month pissing everything away and running around like headless hens instead of simply getting on with the job of building relationships and contacts with the rest of the world outside the EU to slip as seamlessly as possible through the transition.
The EU will not survive in its present form, the writing is on the wall for it. The only questions are whether it can, or is willing to change, or how long the patient will be kept on life support and at what cost to those members who are hell-bent to remain paid up members of that club until they go down with the ship.
