I think more realistic than a trashed economy will be a hyper-neoliberal free market economy with even huger discrepancies between the rich few and the vast majority of poor, with GM crops, terrible workers rights, masses of migrant workers without access to the welfare state, meaningless digital rights, housing and offices in London owned by the world's rich who extract rent from those who live here, and so on. A sorry situation from the perspective of EU rights, but not necessarily a catastrophe from a hardcore-neoliberal perspective.

I'd bet on the UK becoming a low-punching competitor to EU economies, and one they'd perhaps be keen to have on their side.

The question is how we in the UK are transformed by the whole affair.
