I think everything that you say and predict in your post is true, and it will happen.
I had always associated that determined, religious faith style desire to press on and believe, regardless of evidence to the contrary, with left wing political nutters. Brexit has become no different. It’s now bears absolutely no resemblance to the thing it was presented as pre-referendum. Evidence that it might not be a good idea is everywhere, but still we cling to this hope that somehow, by some fluke, we might defy the odds and that thousands won’t suffer the misery of job loss, zero-hours contract re-deployment into “battery-hen” warehouse conditions earning just above minimum wage.
It’s such a massive gamble and still don’t know what the winner collects.
