The federal government is actually quite efficient in what it does. For example, the overhead for Social Security is between 0.5% and 1%. I.E, less than the mutual funds in my 401k charge per yeah for "administrative fees."
When people talk about government waste, what they really are talking about is things the government does which they don't approve of. E.g. ICE--is that wasteful spending? Depends upon whether you like ICE or not. Aide to Israel? Same stuff.
That's why DOGE got nowhere. There is no mythical mammoth waste, fraud, and abuse in the government.
