Yes, the permanent political class is the establishment.
No, the establishment is not “anyone not for your particular person or position.” This false definition is false because it has incorporated the context of relativism, which is in the end meaningless.
The permanent political class is exactly what common sense tells us it is.
It’s so ironic that you are buying the populist swill. Sarah Palin is a career politician and is part of the permanent political class. Had she not been defeated by the DNC machine halfway in her term she would still be in office. If she runs like you and her fans want then she’s simply getting back into the same permanent political establishment she’s preaching against.
Populism
1.
politics unfavorable to elite: politics or political ideology based on the perceived interests of ordinary people, as opposed to those of a privileged elite
2.
focus on ordinary people: focus or emphasis on the lives of ordinary people, e.g. in the arts and in politics
It means-——NOTHING!! It just allows the person speaking or writing it to feel superior.
