I have never worked for the government, but have worked in industry that deals with government employees. One thing that is very different in industry than in government budgets is that industry budgets do have that 10% of waste. But the budgets of all government orgs I have seen are incredibly lean, especially on the salary side. The government gets mission-driven folks that are willing to give up income in order to accomplish the things they want in the world. I saw this most clearly at CDC, all the scientists I interacted with could double their salary over night by going to private industry, but they stayed where they were because they were more interested in doing meaningful and impactful work. And when it came to the budgets that CDC used to accomplish scientific work, they were even more frugal and effective than the most penny-pinching academic labs I saw. Industry is awash in waste in comparison to how effective the dollars were that were spent at CDC.

And the CDC work is all pre-competitive work that boosts the efficacy of everything else in the economy. A tiny amount of money that results in so much more economic activity and savings than could be imagined in most private industry. And all the numbers for the public savings on, say, food safety are all clearly laid out in long reports. Reports that nobody at DOGE would ever read because they don't believe than anything good could be produced by people who accept lower salaries for higher impact.
