That's what I meant by "private contacts." They don't outsource every single possible federal job, otherwise there would be no executive branch left. So the public sector jobs are highly efficient, and the waste has been outsourced to the private contracts where it's more obfuscated.
We could do those jobs much more cheaply and efficiently by nationalizing them, but then that would be "big government," even though it would be saving tax payer dollars when all the accounting was said and done. So 🤷.
