No defending Russian capitalists here, I want them all to be stripped of their wealth and the whole Russian state dismantled and replaced by a democratic socialist one. Those rich Russians should be eaten.
But the fact that the Russian state currently is letting their money get stolen (which they knew would happen when they started this war, and those capitalists knew would happen when Russia started this war, which is why they were begging to avoid it) shows that they aren't oligarchs.
Only the countries stealing this money has oligarchs. And this is also evident by the fact that the money is getting stolen, since it's hurting western governmental institutions. The world's trust in the western system is being traded for more money to the capitalists.
