You are making an assumption that these "competent people" have not been replaced long ago with people loyal to the Deep State and the globalists.
The whole process of "institutional capture" involves slowly replacing people with your own ideological loyalists at all levels. Obama's people were very busy at this all through his administration.
To capture a system by infiltration rather than invasion requires deception due to its inherently evil character.
The overthrow of the infiltrators requires another kind of covert methodology, due to mere practical need. In elevating truth and justice, this form of overthrow is far more powerful
than what the infiltrators have available to them.
