At its core, the Brexit vote was a political act, not an economic one, despite the arguments made by both supporters and opponents of the UK leaving the EU:

Defending Brexit is not the easiest thing to do at the moment when we have a government hell bent on delivering the worst case scenario. It also doesn’t help that the Brexit groupthink produces pretty feeble economic justifications rather than looking at the issue as a whole. Fighting on the enemy’s turf is always a loser and the mainstream Brexiter economic justifications are collapsing. 

I have argued for a long time now that the economy is a secondary concern – and as far as that goes, the aim of the Brexit process should be to minimise what is bound to be economically stressful. Something this government is failing to do.

But then, I repeat, this isn’t an economic question and it never was. It is political, cultural and constitutional. It is said that Brexit has divided the nation but in fact all it has done is exposed a deep cultural chasm that was not being addressed by the status quo. There is a gulf of misunderstanding between the factions and it’s time we dragged it all out for examination.

And then comes this bit, which I found particularly informative:

When we look at that we find that it stems from a collapse of trust in UK institutions. And that can hardly be a surprise. Every major increment in EU membership has been done by subterfuge and deception. Direct consent has never been sought and our interactions in the EU have been yet more deception. Cameron’s phantom veto and the bogus attempts at reform were quite obvious pieces of political theatre from an establishment with no regard to the wishes of the public.

I think that this critique, when taken generally, is also at the core of the right-wing populist movements throughout the western world.

People feel that the sales pitch for increasing global integration have been dishonest, and I’m inclined to agree.
