We have a country (or at least a city) in which Russian oligarchs want to live. Does that count? Can't imagine how that helps the general populace much though, apart from pushing up property prices in central London. Footballers are probably happy about their arrival too, but then they'd be happy if you shone a torch in their eyes and told them it was a portable sun lamp.
It interests me (though not necessarily you) that the first non-British group that is very rich that I could think of is the Russians. I wouldn't have thought of them a decade ago, maybe even five years ago. I'm not sure that, even before the Russians arrived, that many British people would think of the Jews as being rich non-Britons. But then whatever we have here in the way of anti-semitism is more linked to a general dislike of foreigners than any world banking conspiracy theories. More likely we'd have thought of Americans, or even Japanese. Perhaps tomorrow it will be Chinese?
What I'm saying is, I think, that it is anti-Semitism. Largely because it bears no relation to current economic trends but has a lot to do with long-term prejudicial stereotypes.
But he has a messy desk, a comely actress as his general factotum and lots of books, so if I was Japanese I'd probably vote for him, regardless. I'm not sure I'm fully capable of engaging with this democracy business anymore...
