It's almost like the government has already spent decades wringing every last penny of fraud prevention out of the only programs these type of goon wants to cut. Any kind of welfare that benefits regular people has deliberately onerous applications and continual verification. You can cancel these programs entirely, but there's little actual fraud there to find in Medicaid, food stamps, etc. There's actually millions of people who would qualify for these programs that aren't on them due to the difficulties of the application process.
There is plenty of fraud to be found, but it's all in the contraction, consulting, and acquisition sides of the budget. There's plenty of fat to be wrung out of military contractors or contractors like SpaceX. Look at the debacle of the pandemic business-aid loans. But this is the type of waste and fraud that Musk and Trump love. It personally benefits them and everyone in the cabinet. They could find fraud here, but they're not interested in that type of fraud.
