i think it's a cover. smoke and mirrors.
donald trump does not care about fiscal solvency and is not a fiscal conservative. he proved that in his first term. he slashed taxes irresponsibly and generated huge deficits, then shrugged it off, which is the norm for republicans since reagan. republicans always create huge deficits, often largely via war spending, but also via overwhelming corruption. it is true that they cut services for the poor, but this isn't about saving money, it's a type of class warfare. it's also a means of scapegoating that helps them get the working poor and lower middle class to vote for them, against their class interests.
i would expect millions or billions of dollars to disappear in the next four years, or to be spent on weird consultants, and for the money to ultimately be funneled to trump and/or musk. that's the actual point. they're not just making stuff up, they're distracting you from what they're doing by telling it to your face and hoping you can't figure it out.
