Change is coming, adapt or go under, always been that way, always will be.
Yes, but change - any change - has to be gradual, if it is to be of any economic benefit.
The rich and the powerful and those of us with assets outside of the UK will benefit from a violent and sudden Brexit. My dream scenario is Kent becoming a parking lot for lorries and supermarket shelves empty. Riots and a hung parliament unable to move one way or another would be even better (for me!) You could make my day with the Irish boarder being closed and the 'Troubles' kicking off all over again! If you have money and other assets, death and destruction, chaos and turmoil is usually 'A Good Thing'.
Boris as PM - yes! Makes me feel all warm and fuzzy 'down there'!
My family and I, my children, my grandchildren and my wife - we all will still be able to travel and work throughout Europe. When the Blue-Rinse Nazis close the gates, we are OK. We shall be on jam! We have those magic documents rather like a press-pass that lets you into the VIP lounge at a trade fair, that allows us to pass through the gates. We call them German passports!
You and your family are going to be stuck on this side of the gates!
When the communists took over East Germany and called it the DDR, clever people left. What was left was nicknamed 'Der Dumme Rest' (the idiots left behind). DDR did not stand for Deutsche Demokratische Republik, but stood for Der Dumme Rest.
Sadly, I doubt the gates will swing shut and my dream of chaos and disorder will remain just a dream. England will not become a DDR, Scotland will not separate, NI will not join the South and BJ will not end like Mussolini, swinging from a lamppost.
Brexit will join other temporary fits of national madness, like the Millennium Bug and electric cars and melt away like the snows of Winter.
Or as HG Wells put it "Today's emergency is tomorrow's joke!"
