The UK wasn't in the Eurozone - and I've been reading Yanis Varoufakis's books about his time as the finance minister of Greece and I've been fairly shocked at how fundamentally undemocratic (not to say unreasonable) a lot of EU institutions and the likes of the IMF are.

And I say that as someone who voted Remain in the Brexit referendum (note that Varoufakis actually campaigned on the Remain side in the UK).
