Go to any finance or ID card office and tell me that 20% of that workforce couldn’t be culled and achieve the same level of output.
My main experience with civilians before I got to DC was those same folks, and I often wondered the same thing...until I was the Admin O of my second squadron and had to deal with admin BS all the time and finally understood why many of those folks were so surly.
After getting to a staff job and subsequently transitioning to the civil service myself I saw that there was more to our civilian workforce than PSD and ID folks, and cutting 20% of the folks that I work with would do nothing but seriously degrade our country's defense capabilities. Can some trimming of the workforce take place across the government? Sure, but it should be done as part of a deliberative and careful process to ensure we keep the capabilities and resources we need and not in a haphazard and abrupt fashion that originates from tweets by randos and morons.
Our acquisitions process is yet another example of the same systemic issue we have, people and corps are not asked to perform to any real metric and failure doesn’t hurt.
There is a lot more to our acquisitions process than civil servants being a pain in the ass with a raft of laws, rules, regulations that govern the process along with Congress involved that make everything the way it is.
