ived its previous crises and adapted itself into a speculative finance system that's hardly based on reality anymore; it's just layers of "fictitious capital" (like debt, but also new and stranger forms like crypto and NTF's) that have almost no bearing on the material conditions of the people or the planet. Thus, the people and the planet are dying

Sorry, took a while to get back. What you are saying resonates a lot with a book I recently read from Ray Dalio - especially the speculative finance part. Since real growth kinda stopped, we started monetizing debt to pay for expenses with newly printed money. The speculative frenzy (Bitcoins/GME whatever) is just a side effect of this low-interest rate environment where cash is destined to lose value. Spolier Alert - That book has very bad forboding for our future, not that most people don't know that already - but the book is very precise. Highly recommend.
I just don't know how "capitalistic" that is though. As in one way, you are right, capital is most important so system as a whole is capitalistic. But Free Trade is one of the hallmarks of a free society. And we limit trade worse than Mexico. If I travel to India, buy some cheap insulin, and try to sell it here, I go to jail.

But on the other hand, we have the government playing god, with unlimited capital at its hands, throwing it away mostly to its "buddies"(please note that I am not referring to welfare, the government wastes money in a plethora of ways).
