And here he has a point. No, “the system” doesn’t compel the likes of Green to behave as they do; “the system” didn’t put a gun to his head and force him to become a tax exile;
Jones is obviously using “tax exile” in a pejorative sense here. And as far as I know Green isn’t a tax exile. He’s both resident and domiciled (the latter I’m not sure about) in the UK for tax purposes. There is actually no manner in which a British citizen, born in Britain, can be a tax exile while working in London every week and drawing an income from a British source. It’s simply not possible.
