El establishment: the establishment

“There are millions and millions of people who are tired of establishment politics, who are tired of corporate greed, who want a candidate that will help lead a mass movement in this country…” / “Hay millones y millones de personas que están hartas de la política del establishment, que se cansan de la codicia corporativa, que buscan a un candidato que les ayudara a guiar un movimiento masivo en este país…”

I’ve heard this usage in Argentinean media—I say this in case it is a regionalism.

I’ve seen other translations, like establishment: el statu quo and el establecimiento but I’ve never heard anyone say either of those.

I suppose “la clase dirigente/dominante” could work but it seems to refer to a class of people (“the ruling class”), whereas “the establishment” refers to those people and the systems they use to maintain power, like the government, private financial systems, etc.
