It's not all about economics right? Its about other stuff like..........?
For me it's bigger than economics, but a big part of our arguments have been about the economics so if we're wrong then you guys can certainly be unbearably smug about that. It won't happen because the economics are the clearest area of fault in your arguments, but hey.
The rest is a much more unclear picture of influence and power and who will be wielding it in the coming decades. It will have huge economic impacts, but it's also larger than that. Most Brexiteers appear to believe that the UK will continue to hold considerable influence in the years to come, whereas from my perspective the future is competing power blocs (US, EU, China, Russia). There isn't much point debating the details at the moment because it's too early and will inevitably lead to mockery/accusations of scaremongering. Suffice to say that I see the world heating up (in more ways than one) as the new superpowers flex their muscles and start to break free of American hegemony. We're already seeing this very clearly with Russia. The safest place for the U.K. in that scenario in my opinion is as part of an EU bloc that can separate itself from US interests to whatever degree it chooses, and not get dragged into an East vs West confrontation.
