“Populist” is a disparaging term used by authoritarian status-seekers to dismiss the right of the people to govern on the basis democratic and egalitarian principles.
Authoritarianism is the redoubt of individuals whose meagre practical talents are insufficient to support them (e.g. Adolph Hitler was a mediocre artist) and, in consequence, they have a need to persuade or coerce someone to do their bidding and sustain them. What to do with immodest ne’er do wells is a persistent problem. Perhaps it even gets worse in relatively successful communities because there is a material surplus for them to access without being noticed.
