As the death penalty, personally I'm not a fan. But I am a fan of severe punishments for the kind of intentional corporate malfeasance we're talking about.
Here's the lesson I'd like people to take from all of this: markets need strong voernments to function. Libertarianism is a fantasy with no basis in reality (eg [1]). Political movements such as "starving the beast" [2] are nothing more than an attempt to extract even more profits from the populace, even to the point where that society can no longer function because no one can afford food or housing, the drinking water is poisonous and none of the roads or bridges can be repaired.

I don't think any category of crime has ever been eradicated from anywhere. The question is whether China's measures reduce corruption. My bet would be yes, but who knows.
