Why don't American oligarchs fear the consequences of their corruption, and how can that be changed?

Although I remain sunk in doom at times , I am at last beginning to see an increasing number of people - not yet in, but getting closer to the mainstream media, who are putting their thoughts together and into words:

Why don't American oligarchs fear the consequences of their corruption, and how can that be changed?

I see no evidence that “rich people are very, very afraid” — at least not by their actions. And that, to me, is the problem. That fear — a lot more of it — is necessary. Their ability to rope themselves off from the society they are degrading, combined with the para-militarization of domestic police forces (aggressively displayed in response to the Occupy movement and related protests), and the rapidly increasing domestic powers of surveillance and detention (designed to intimidate the citizenry and thus deter and guard against mass protests), have convinced them, I think, that they need not fear any protest movements or social unrest, that America can and will become more and more of a police state to suppress it. An elite class that is free to operate without limits — whether limits imposed by the rule of law or fear of the responses from those harmed by their behavior — is an elite class that will plunder, degrade, and cheat at will, and act endlessly to fortify its own power.

My comment:
I asked myself if this language is too extreme, but I really DON'T see any fear, no thought of what happens when the number of people without health care hits 50%, what happens when people steal enough copper to affect the grid, what happens if enough people are excluded from voting to delegitimize the system, what happens if private security - including bribes - for rich people becomes a necessity.
