I just don’t know how someone could possibly think this is a good thing unless they are in the executive branch reaping the direct benefits
Reading up on the history of the Unitary Executive Theory may provide some background: https://en.wikipedia.org/wiki/Unitary_executive_theory
In this case, Trump is easily bought and isn't very concerned with governing himself (compared to playing golf or designing ballrooms). With this in mind, even people outside the executive branch, or even the USA are benefiting.
That's always the question with this unitary executive business. They believe this is the government defined by the Constitution, regardless of precedent. Do they believe it is a good system of government? Do they believe this is the government intended or rather the government allowed by legal loophole, vagueness, or contradiction? Because it seems like they think the president should rule like a monarch because they happen to control the presidency at the current moment, not because it is a wise and effective system of government.
It depends on whether you think elections are better than “independent civil servants.” The system the founders created was one where the executive branch would be subject to the whims of the people via regular elections of the President.
In the late 19th and early 20th century, folks like Woodrow Wilson came up with this idea of the administrative state run by independent expert civil servants: https://teachingamericanhistory.org/document/the-study-of-ad.... The concept arose from Wilson’s hatred of democracy and immigration:
> The bulk of mankind is rigidly unphilosophical, and nowadays the bulk of mankind votes. A truth must become not only plain but also commonplace before it will be seen by the people who go to their work very early in the morning; and not to act upon it must involve great and pinching inconveniences before these same people will make up their minds to act upon it.
> And where is this unphilosophical bulk of mankind more multifarious in its composition than in the United States? To know the public mind of this country, one must know the mind, not of Americans of the older stocks only, but also of Irishmen, of Germans, of Negroes. In order to get a footing for new doctrine, one must influence minds cast in every mold of race, minds inheriting every bias of environment, warped by the histories of a score of different nations, warmed or chilled, closed or expanded by almost every climate of the globe.
The idea of “independent agencies” staffed by neutral civil servants arises directly from this skepticism of democracy and voters.
