Additionally if you want to selectively quote statistics I can just come back with 4 out of the top 10 are EU nations. 7 out of the top 10 have to follow EU rules.
The EU forms 510/743 millions of people in Europe, so GP's point is more valid than you claim.
Edit: and that's without even addressing the ridiculous straw man of "autonomy" (all sovereign countries are autonomous - no country is forced to be or remain an EU member against their will)
Though if you want to actually look at the information all the nordics are in there of which 3 are in the EU and 2 are in the EEA.
Brexit is comparable to the Berlin Wall falling. Like the Soviet Union, the technocratic elites could not imagine it collapsing until the people willed it.
The lack of freedom for Greece to manage its finances is because it's a member of the Euro, not the EU. That isn't really relevant to the UK.
And as far as I know, neither the Euro nor EU laws limited the Greeks' ability to prosecute their bankers. Is there a reason those are connected?
Same could be said for Ireland[1]. You might wanna take a closer look.
In the words of M. Thatcher: "He who controls interest rates in Europe, controls Europe."
"Relatively small", because UBS was warning the Greece faced hyperinflation, military coup, civil war — and that was just from leaving the Euro and revaluing their currency in an orderly default where they didn't have to repay everything.
It's not just the EU that told Greece what to do, the IMF is part of the Trokia.
Cheers.
