I have to agree with everybody else in this thread, not a big fan of blaming the people of Russia for what their dictator does; even if they are in his so called "inner circle". Perhaps these people can pressure Putin to change his mind, but he doesn't look like a humble man looking for advice.
It is a weird development, but all things considered not the worst thing that's happening.
I agree, not a big thing, and I certainly think people with that kind of wealth know more about hiding money than the rest of us will ever know, and this war will probably not affect their wealth too much. They probably all knew in advance and shorted some Russian stock on the London stock exchange - making a killing. I do find it a bit strange that we "cheer on" this seizure of property based on nationality though; but most probably think it's ok since they are so obscenely rich.
If I am forced to return and work in Russian IT (seeing as I would also not be able to get paid by overseas customers due to sanctions), we both know which government's war this would support.
