I dont see how Jeff or Elon are oligarchs in the sense of russian oligarchs.
The Intercept isn't exactly known for... neutral... reporting.
"Agency managers originally hoped to award follow-on HLS contracts to two of the companies to encourage competition and protect against the possibility of major problems or delays that might affect one company but not the other.
But Congress only allocated $850 million in NASA's fiscal 2021 budget for lander development, about one quarter of the amount the agency said it needed to have a new vehicle ready by 2024.
Given the available money and projected future spending, NASA "down selected" to a single contractor — SpaceX — deciding the California rocket builder offered the most attractive combination of cost, technology and management expertise."
Neutrality may always have some element of manufacture, but that doesn't mean it's equivalent to intentionally trying to generate partisan outrage. This isn't a "bailout fund for Jeff Bezos" — word-for-word quote from the headline of the Intercept article! — it's just NASA continuing to try to get budget for the projects it wanted all along, so it can have redundant contractors like it did with the commercial crew program and avoid getting stuck with monopolist pricing (and monopolist poor performance) like it nearly did with Boeing.
While it’s a fun jibe to throw at them it’s a completely different thing to just being insanely wealthy through actually doing something effectively (if sometimes immorally)
Still, the term implies politics... not just money. I would also hazard that it implies hereditary power. You could argue that dynastic politicians are oligarch. I'm not really disputing, just pondering.
Ultimately, for both Russians and Americans, oligarch is a (usually derogatory) analogy. It's not a formal oligarchy. We could also say aristocrats, which is more appealing to me.
Also, there's an idea that all governments, or systems of power are oligarchies. No matter what the formal system of government, some group of powerful people wield a lot of power. Rich people, religious leaders, senators, backscene power brokers, generals...
Bezos or Koch or Hamm or DeVoss can't move their American levers as far, but the overall output is quite substantial compared to what Abramovich can achieve with his.
