Simon Kuper (FT) suggests the one thing that #Brexit has delivered is a realistic assessment of the UK's place in the world:

'at last, the UK knows what it is: a small country that needs immigrants, high taxes & European allies... The government lags behind ordinary people in absorbing this self-knowledge'!

I think this re-assesment might have come earlier if people (and the media especially) had focussed not on headline GDP (ranked 6th-ish) but GDP-per capita (around 22nd in the world!) 

 @43d7c4ea I think that’s optimistic. As far as I can see, British exceptionalism is as alive and well as ever, in those who believed in it pre-Brexit.
