//Krom, but the argument is not restricted to trade. That’s the point. The Remainers, in order to bolster their argument, can continue to pretend it is - but it isn't. It's far more than that.//
Yeah, I know. I'm not claiming it is. It's just you were asking how countries outside the EU prosper, and that's the answer. They do it through structures that are remarkably similar to the economic functions of the EU (which is still the main part of its work). We can have the discussion about political union if you want (in my opinion not 100% a problem), but it is a different discussion to "why do other countries not in the EU prosper?", which is what you asked.
It's really difficult to have a discussion if you're going to keep shifting the goal posts.
