And by the way the UK will NOT reduce workers rights, whatever you say most of the EU law about human rights came directly out of London!
Secondly we are suited to a more outward looking model, certainly banking and trading will really thrive. Yes you will lose some jobs, but once we are out, we are out and can expand with the EU bureaucracy.
The border problem we dealt with some time ago, and I can't see that being any problem if both sides are willing.
Lastly the four quarters of the union splitting up. Well Wales voted to leave so they aren't going anywhere, same with DUP they are very pro leave, so that leaves Scotland. And quite frankly the independence issues have been rumbling on for years pre brexit, and will rumble on for years post brexit. In the end, they are unlikely to leave the union (but can if they want to of course, a matter for them)
So in the end we will get over these hurdles, and we will have our country back, and for most of us this is the most important thing.
