Lets just disagree. I see a lot more enthusiasm for the task and a lot more information revealed to the public in two weeks than all of IG's combined output in 2024. And I don't blame the IG's either. The IG's meticulous investigative reports and recommendations were largely ignored - quite similar to the NTSB guy lamenting the FAA's disregard for most of their safety recommendations.

You just hit on WHY Trump fired them. What purpose did they serve?
They worked out of the groups they were auditing - how much truth-telling could they really do?

Literally no one in America would say that the US Federal Government is a model of efficiency and stellar customer service. Even the most strident DeepState apologists here won't go that far (although now that I've typed this, one of them will do it).

Form up a Inspector General corps within the exec branch whose job it is to evaluate performance and efficiency of each branch. Then rotate the people who do the investigating around such that they don't get too attached to the groups they're monitoring <--- this is how it's done in corporate America.

The left will shriek, "Bbbbbut then they won't have any institutional knowledge of who they're reporting on!" The answer to that is to hold these departments to objective standards - like say, being able to account for their money - and hold them to it.
