I don't work directly for the US government but for a government contractor. It is a services contract so we ( meaning I ) work with federal and contractor employees every day.
I can tell you that it's hit or miss with the quality and integrity of both government
and contractor employees.
Some are very conscientious and honest while others are criminally complacent. Most are somewhere just below middle so on average you have mediocracy at best.
I could write volumes on the corruption, deception, waste of resources, and fraud I've seen go down.
And, no, it won't get fixed. It won't allow itself to be fixed so the only thing left is to control its growth.
So the question is how much of your life do you really want to have run by mediocre bureaucrats?

Up until 1968 I to worked for firms contracting with governments (federal and state). I saw so much crap that it sickened me, so I vowed right then and their never to work for a firm that does business with the United States. From then on I worked as a contractor for purely private firms that did not do government contract work. I earned a good living and I was finally quit of government work. I worked for over 35 years without taking a cent by way of a government contract. I rendered myself squeaky clean.
