While I get that in the corporate world, you can hire and fire unencumbered, and be as iron fisted as you like, the office of POTUS, despite Biden's numerous attempts, does not--and is not supposed to--work that way.
That is what the Constitution is for, for good or ill, to slow the changes brought by diffusing power. While that power has, unfortunately and likely unconstitutionally, been concentrated at the Federal level far beyond original intent, only relinquishing that power to the States might be effected with any rapidity by dissolving Executive Branch Departments, and reorganizing the rest. I am not sure how much power the POTUS has to do that in the face of Congressional objection, but it would be a good start. Much of the deep state is ensconced there (though hardly all of it), and eliminating those positions would likely be easier than eliminating the personnel entrenched in them.
