I think the OPs point was “deep state” has a deliberate, highly charged, negative connotation.
Don’t conflate the horrible reality of racism with the historical origin of a racial insult. The OP is merely using it as an example to illustrate how terms acquire meaning through time and social norms. Not excuse their existence.
My point is that words have meaning based on who uses the word. The N-word is used by racists and is now avoided by polite society (unless you wish to explicitly label yourself a racist)
"Deep State" is used by conspiracy theorists who wish to destroy government workers and their positions. Its a phrase that should be avoided unless you wish to paint yourself a conspiracy theorist.
It’s a pipeline and someone has their hands on the valves.
For instance, in Washington DC there is certainly a pipeline from public to private to high level to lobbying to etc., but I think what the +parent posters is referring to encompasses the scientists at the EPA and the USDA, the doctors and nurses and managers at the VA, etc etc. They tend to get a job there after a bit of moving around and then stay 40 years. There is no trading out to private sector -- they generally get a gov't job because of a combined desire for altruism and good benefits and stability -- and the vast majority would never even be offered, much less accept, a lobbying position.
Source: family in such positions, who just want to examine and regulate the wastewater output of cheese factories in the heartland and go home after a good day's work. Said member was forced out of their job recently due to politics -- not "business-friendly" enough.
Now you’re replying to me about high-level HR decisions biasing the processes of government agencies. I don’t think there is anything to elaborate?
Instead of using "Deep State", it might be better to say "Agency Directors", if you wanted to use neutral language. "Deep State" is loaded. Of course, its more popular these days to value-signal which side of an argument you're on, rather than appearing neutral...
In any effect, the people who use the word "Deep State" wish to imply that government workers have their own agendas. In my experience however, government workers overwhelmingly just want to do a good job with the task they've been assigned (much like any other human who are tasked with a job).
