Just because the chinese oligarchs give themselves government titles and the US oligarchs do not is no reason to believe they're not the ones in control.
That being said they are also highly disparate with a variety of motivations and are incredibly hard to whip (using this the way its used in congress) into directions that are nuanced. Things like "we wanna make more money" "regulations/unions are bad" ofc oligarchs in the US manage to see eye to eye on, but anything further nuanced - that class discipline - is harder to achieve in the US than China
