I will start with "Parasitocracy", that great term you brought here. Most awake observers would agree to at least some degree that those who hold the power (or who are The Elite, those who are very rich, etc.) are always gaming the system so they can make even MOAR. Or get moar power for themselves. This has been going on for millennia, and I don't think it is necessary to bring further proof to this discussion, it has been proven "enough".

Though here's the thing... it's one thing to think (and even 'know') the system is rigged, but it's important to understand exactly how.
Without knowing how, people tend to demand solutions, like electing a socialist or a Trump, which will likely make things worse.
The powers that be have a narrative (propagated by the educational system and conventional media) that we in the West live under true democracy and free markets. So those who 'have' deserve everything they get, because others either voted for them or voluntarily bought what they have to offer.
It's imperative to destroy this myth by phrasing the problem in a succinct but rigorous fashion. Otherwise, the prevailing view will be that free markets aren't working, so let's give even more power to the elites.
Mmm-hmm. But, defining how the system is rigged is rather more difficult than it might seem. Part of the problem might be a semantic issue: "Rigged", what exactly does that mean? I like the term "narrative" that seems to have gotten popular say a year ago, and it seems to describe the propaganda that we all must bear. But, I agree, there is a "consensus reality" that seems to be shared by The Elite and the MSM (Mainstream Media).
This go 'round re president is not very promising. BOTH will likely spend lots & lots of money, that is one of a few shared positions (but spend on different things).
I will leave the words "democracy" and "representative republic" alone, further discussion of those two might resolve your comment re democracy.
However, "free markets" are an ideal, it could be argued that on-and-off the USA has come pretty close. Clearly we are not very close to the ideal now. And both Trump and $hillary (ahh, whom would I be for?) would hinder free market activity, the former by his opposition to the TPP (which may be a bad treaty, especially if that is the one that is
secret). Hyena Rodent is a proven liar, and has been for 30 years. Trump would be a High Risk President, who might run us off the rails with a bad decision or two...
As a general rule, the more libertarian, the better. Fewer restrictions on our economic and political freedoms, the better. The contrary (bigger government, concentration of power, etc.), the worse.
I still the think the term "parasitocracy" that you introduced here is an excellent one-word summary of many flaws in our system.

Bitcoin's price crash today (which I just read about, "Mi Reina" and I were out running errands) is relevant here. BTC is reasonably beyond easy control by The Establishment. And so takes another black eye. I do feel a little better having spent some BTC for gold when BTC was at $690 and $660. Maybe the time has come to buy again?
