Russia isn't an oligarchy.
Oligarchy is when the select few rich have political power.
Which is the one thing Putin doesn't allow the rich of Russia to have.
Dictatorship? Sure. Authoritarian? Sure.
But oligarchy is just propaganda against Russia. Even before president Musk America was far far more oligarchic.
It's obvious you haven't looked at BYD cars. The American autoindustry is dead, or it will be everywhere but here.
