You could say so, but this also guarantees a more prolonged stable economy in the long term and the national bourgeoisie (what you call the oligarchs), are not so deep rooted as they are in the US, for example, Russia has inherited a relatively strong State infrastructure and mechanisms from the USSR, so they can't do whatever they want (although of course they influence very much). If they can guarantee the stability, by the looks of it, they could win in other scenarios where Russia starts being an even more important international player, so they could cover costs for profits in the future.
