I am Eugene, so keep that in mind…
I see people who get into this "capitalism as psychic Landian egregore" as people who have become so fixated on abstractions and bad interpretations of German philosophy or liberalism that they lost sight of anything. It's basically Ingsoc shit, and once it takes root, you can't really say no to it. At some point these abstractions refer to something people actually care about. Anyone in business, anyone who has a going concern, is not a mindless actor chasing abstractions. I don't know why this idea is promoted so heavily, and really it is only in internet echo chambers that this is believed. Unfortunately, many people only have those echo chambers, and any time they contend with something substantive, there are agents ready to "correct" this brief sanity.
The idea that capitalists are dealing with the same abstractions as cloistered academics wishing to cajole revolution into existence, is misunderstand what is at stake, and why this situation exists in the first place. So far as "degrowth" has an actual purpose - and you have to bear in mind that depopulation and eugenics are in the past 50 years the overt policy of the ruling institutions and they will tell you this if you want to get anywhere in this world - the aim appears to be eliminating "zombie firms" which no longer serve any genuine purpose in managing labor and the wealth towards the aims that dominate in the present society. Capitalism is not a "mindless system", where the capitalist himself is an abstration unaware of the world he lives in, or the ideas that he is responding to in the market environment. From the start, the capitalist has aims that are not the system "for its own sake". That's what imperialism in the 19th century was - it was a belief that the disorganized market activity of smaller producers would be subordinated to the imperial mission and the large trading interests, and the affairs of corporate states like the East India Company take precedence over the interest of industrialists. The industrialists are not for the "capitalist system" - they hate being in hock to banks and spent great effort fighting the bank, until they could command the bank themselves and become the villain. This is one thing that was contested in the American Civil War - the slave power held the banks, and the new men and robber barons wanted to become the bank, for perfectly understandable reasons. There isn't a unicorn world where you have no bank and everyone sings a happy song like they're children on Barney and Friends. That is the nature of what it means to engage in economic life, and this is not particular to capitalism. Communist states and socialist states would have banks and centers of finance and management, because that is what it means to engage in any political-economic activity. It may be a more benign bank which recognizes the benefit of human freedom to act, but in all societies, there is a way in which economic life is reconciled with the state or the status quo in society. The hand of states in the past was looser, but the state's officers were always aware of the situation they were in. The Tsar of Russia and his court were not stupid men who were cajoled into a revolution by ignorance - it took Russia being ground down in WW1 for three years to bring about a liberal revolution, and part of this was an unwillingness of Nicholas to continue ruling under these conditions, against what the war would require him to do. It was also clear that Russia could not win that war - that they were being sacrificed as Germany gained the upper hand, even if the Tsar or the liberal government insisted they would totally win. The power of states and armies trumps any ideology or conspiracy of global elites in the final analysis, and nothing in Russia stops the German army from running roughshod over Russia in 1917. That's one reason why Lenin is really pro-German in the early USSR - he knows he's going to have to lick German boot to get out of this one, if he wants peace as he surely does. Anyway the point of this is that it is very easy for these abstractions to give way to the realities of war and politics. The abstract thinking that suggests you can deal with these things in the way that Malthusians do is the result of mental illness and a disconnect from anything we actually do in economic life.
Like I said, the main objective of degrowth, so far as it is a real policy, is to liquidate the failing firms which no longer serve a real purpose. They will tell you this and make that clear if you follow the news - you don't really need Sears or much of retail in the world where Amazon Fulfillment Centers are a superior option. You don't need a lot of old factories producing things which are no longer necessary or desired. To make new factories requires liquidating businesses which have property and interests tied to the old factory. The oldthinkers don't have any real force in the state now, and have been told to keep their head down and shut up, and what is happening is their liquidation from all sides. The center just relies on liberal smug and the imperial religion of eugenics. The left uses "degrowth" to push the center's interest. The right, who in the end will do what fascism requires, sells decoupling of the wage fund from capital, which effectively changes the payout for productive capital and labor to chits exchangeable for goods as the Amazon Company Store - basically, the Right's leaders are selling full economic slavery and maximal managerialism, and because the Right is a slave race - and they do see themselves as racial rather than national or societal, and races are always defined by their lowest common denominator - they are pushing hard the most miserable conditions possible. So you have a situation where the left and right and both pushing maximal depopulation and slavery positions, making the center the "default" choice. This is only possible with full control over society and policing anyone who says there is anything other than these three options - and it is always three options, following a model Germanic thought isolated and perfected to control history and set it to a preferred state in the mind of the slave race.
