If that's what it turns out to be, that no matter what happens politically, the government absolutely cannot do anything to bring its spending under control, then the US is effectively a failed state, and in that case, DOGE's role is a diagnostician.
But I seriously doubt that's the case. What's more likely is that it is perfectly possible to bring spending under control, and that the people who are complaining are doing so because they've had their lips taken off the teat.
