Whatever you are reading is badly misinforming you.

I'm sure there was some reform and cleanup to do in certain USAID programs, but the programs Musk killed or interrupted were literally the best lives-saved-per-dollar programs on the planet. PEPFAR, for example, is credited with saving 25+ million lives since it was created during GWB's term.

There's also the rather important point that what Musk did was totally illegal. These are programs created by congress and their funding is mandated by law.
