What have they done to earn my trust? Why would I choose to outsource critical decisions pertaining to my own life and affairs to strangers who are not meaningfully accountable to me and have no direct understanding of my values or interests, regardless of how well-intentioned they may be?
What possible reason could there be to give civil servants authority to make decisions that materially impact us without any oversight or accountability?
Therefore, when civil servants are put into place from the other side, they can't complain.
I don’t think they lose the right to complain.
So then actually, yes the ruling was correct, and yes people are right to put this power back into the hands of congress, and out of the hands of civil servants.
Whatever terrible thing that someone would be complaining about in the future, it is mitigated by this correct ruling that helps stop that supposedly bad thing.
If you want to accept that position that I just laid out, then fine. You agree with me, but you would also be agreeing with the supreme court decision.
Though I couldn't easily find any hard statistics, which may not exist for Hatch Act reasons or otherwise, I'd rate the current composition of the DC-centered civil service at around 70-80% Democrats; defense and intelligence a little lower, health and social services a little higher. If current trends continue, this will reach 90% in many agencies within a decade.
Whether this is a problem or not is a different matter. It is obviously not representative of the country as a whole, though that is only based on a rather shallow and one-dimensional analysis. However, it explains at least part of why this is happening.
