I largely consider Trump a symptom of a larger disorder, I think it is lazy to assume that he and his administration is the source of the breakdown here.
Two thinkers come to mind to me in this case:
1. Hannah Arendt, particularly her writing in The Human Condition (and maybe as an analogue: the Anthony Downs book on Bureaucracy and perhaps Jacques Ellul's The Technological Society I think?):
> Bureaucracy is the form of government in which everybody is deprived of political freedom, of the power to act; for the rule by Nobody is not no-rule, and where all are equally powerless we have a tyranny without a tyrant.
Another comment talks about accountability, but a bureau is composed of people "just doing their jobs" without the personal accountability that helps keep systems accountable.
Per Downs, bureaus eventually become mainly obsessed with their own survival over their original mandate, and it requires careful design to avoid this consequence.
2. Christopher Lasch: The idea that government institutions are required to force an centralized objectivity for democracy to survive is just about the opposite of what I think we actually need, per Lasch:
> "[Specialized expertise is] the antithesis of democracy."
> "Democracy works best when men and women do things for themselves, with the help of their friends and neighbors, instead of depending on the state."
The attitude as espoused in this essay will not do any work to re-establish trust with Americans, it continues a long line of unaccountability or reflectiveness from the "adults in the room" on their own contributions to the degradation of the system by pretending Republicans or Trump are a unique aberration.
