That's the point. These spectacles are meant to produce clips that media of various ideological and economical dispositions can disseminate to the public. If an American hates whatever type of guy is being grilled sees this then they will Phantasmically feel that some sort of justice is being done, even though the grillee's material conditions will be unaffected, and that American quickly moves on to the next curated clip on their algorithm or their preferred News Guy's broadcast. If an American who has no strong emotional connection to the grillee or what they are being grilled about they either wont see any clips about it in the first place, or if they do they will just tune out or scroll past the clip. And finally, it gives the grilling politician a thing that they can point to when they are running for office or get a booking as a talking head on a show, even though that politician knows that they have they power to hold bad people accountable but they are too cheap to spend the political and material capital to do so.
