The deep state bureaucracy is so deeply entrenched, that it can't be replaced, even if some wants to, but only led and purified a bit, to become more streamlined for a better purpose.
There is a general misconception about qualification by the way, because it doesn't help, in any field, if a person has great skills, if this person works against you and your interests. In fact, the more skilled your opponents are, the worse. Having people with experience and skills is therefore only a good thing, if they have good intentions. But the Washington deep state has no good intentions for anybody but their sponsors, which is the main problem to begin with, and a big reason people voted for Trump, because despite all his faults, he sold his "I'm not part of THIS deep state establishment" which works against the interest of the common Americans the best - of the available candidates.
