Bad news.
There is something called the Civil Service Act that prevent firings of government employees without mountains of paperwork.
Prior to this, government jobs were “spoils.” When the old administration went out, the new administration fired everybody and gave government jobs to their friends and supporters.
I am no longer certain which situation is worse.
Yes, this is a major hurdle.
How, though, is it a factor if whole agencies are removed?
If not, then I suppose the issue is the near impossibility to abolish a whole agency.
This was attempted during Reagan years, and AFAIK, agencies slated for the chopping block, due to opposition, had to merely be scaled back.
GOOD NEWS, there is SOMETHING CALLED the VETO! VETO EVERYTHING and watch the PORKY PIG BASTARDS called “Congressman’ and “Senators” SQUEAL!
