As you say, Teribus, we both know and understand the UK has not been in a business vacuum for the last 43 years. But we also both know that one of the things stopping it being a vaccuum was the relationship with the EU. Losing that has an effect. I was quite conciliatory in saying we might not know exactly what for decades. But I stand by what I said: being successful before the existance of the EU is no reason to assume we will be without it. Maybe we will, maybe we won't: time will tell but simply asserting all will be ok is not enough.
