This looks like splitting, or you're deliberately failing to understand how lawmaking works and the importance of making informed decisions at the federal level, in the long term.
Congress constantly grills CEOs, the elite, and victims because it is understood that they reshape society, sometimes for the worse, not always on purpose.
Is a law needed? How do we tax it? Who is being harmed? What is the harm? Can a law be enforced?
The transparency is by default. Not a "spectacle".
I can remember being in high school, still in the age of minority, and feeling joy when one of the louder, dumber cooks finally kicked off.
I kind of suspect Beijing and the CCP of not being so colorful at the federal level, and rather just being a giant executive bureaucracy with principle, law, and regulation intermixed freely, minimal federation, which leaves them largely ignored by society and festering until they're in your face enforcing lock downs -- like an authoritarian military state.
I unfortunately don't read a lick of Mandarin, and I'm not sure where to get a more optimistic view about what goes on over there, but I'm curious.
The reason you don't know it is because the CEOs of the biggest corporations in the world don't live there, so it doesn't get any media attention.
Who cares about the grilling of the CEO of Royal Mail in the UK?
If you do, here you can watch it
You can't generalize the whole thing as spectacle just because a few of the congressmen choose to grandstand / push an agenda / be generally tonedeaf, I can almost guess that in 6 hours at least some of the concerns are legitimate and merit public discourse even if they are nuanced, possibly quite boring, and have more to do with how OS maintainers and parents should behave.
Everything is in the crosshairs and nothing material is sacred, and it has been that way for as long as I can remember[0]. That's why we hire these people.
