Isn't that generally what happens in most developing countries regardless, e.g. you put your wealth somewhere where it's safe?

I would assume Swiss and Luxembourg based banks these days have a lot more clients from ex-ussr countries than say the US and EU countries, because there is greater risk of confiscation (in different ways) of assets in those countries.

If you managed to somehow (honestly) make $50m in Russia, would you really keep it in Russia? I think the answer is probably no.
