You seem to think that every government agency does highly specialized incredibly specific work that you couldn't possibly have any idea how to manage. That's absolutely not the case. Sure there are absolutely certain jobs etc. where that may be the case - certain engineering departments in perhaps DOE come to mind, that sort of thing.
99% of the government is not that. It's paperwork, databases, forms. Not saying it's not important work, I'm saying it doesn't take a genius to look at the workflow for the vast majority of the government and understand it, and see opportunities for better efficiency.
Paperwork, with a mind-numbing set of rules you need to pay attention to, that can affect people's lives in very serious ways. Just a couple days back a guy with protected status was deported to a gulag in El Salvador by a "clerical error".
I lost the thread a bit. Are we talking about Doge? Yes that is a abysmal. No defence for that.
But in general people need to learn some stuff on the job. E.g. hire an 18 year old hacker and by 20 they are leading projects, debugging code, preparing for SOC compliance etc. Is possible.
How many years of training were that?
