Not sure how long we have until Biden pivots towards the OILagarchs (sorry) but the fact that US troops are apparently being pulled out of the kingdom is like a dream come true. We truly live in a time of qualitative change. The world is shifting polarity faster than the US can keep up. These maneuvers by OPEC+ are such a game changer because it softens the benefits that the US is getting from the situation in Europe. Anything that infuriates the US like this has to be worth paying attention to anyway.
In addition to what you said, the homo oeconomicus is a myth, capitalists often do not make rational decisions, especially when things are going to shit. And there is one widespread but terryfying trend in business when they don’t think “how much profit we can get” but “how do we stay ahead of everyone else” - i already read on reddit (also Rainer Shea mentioned it iirc) that China have only 200 nuclear warheads while US have thousands and that the first strike without mutual destruction is possible. Some of them already think that it is better to keep hegemony over partially ruined world than to be relegated to regional power in the prosperous one.
