'Totally won' means there's nowhere to go but down.
Resource depletion and pollution might be their formidable enemies.
You're conveying an image of handwringing illuminati in a room who are out to get us. Is that what you mean? If not, who has been engineering this and why?
This is a popular line of thought (try googling "corporation evolutionary biology", which gets you to pages like https://hbr.org/2016/01/the-biology-of-corporate-survival ), but it has a weakness: it's hard to be rigorous. In the field of evolutionary biology, experiments are hard to design and hypotheses are hard to falsify, so a lot of the writing is deeply infected by the author's prejudices.
I'm sure there's something there, and I'm confident that whatever it is is more plausible than fragile conspiracy theories like the Illuminati. But exactly how non-biological entities compete and evolve is hard to say.

Hadn't heard of it. Just read it. Interesting stuff.
It's very clearly a call-to-arms for business leaders against Marxists/communists. Not the working class.
Most Communists, at least in the West, spring from the middle- and upper-middle class, not the working class.
And Communist countries, historically, tend to make their working classes worse off, not better.
Equating a defense against communism with an attack on the working class would seem a stretch.
In the Powell memo, you can see some of the precursors to what's happening today. For instance, I think the demonization of academia in right-wing circles as well as the death of organized labor (unions) probably start with this memo (I'm not the only person who thinks this. Chomsky as elaborated on this at length.)
The Powell memo was also started the process of making lobbying both widespread and acceptable to society (even when it was legal, it used to be frowned upon.) I think most people would agree that lobbying is a cancer on our democracy.
In economic theory "the gravity of capital" dictates that lumps of capital attract more capital- the larger the lump, the larger the attraction. Once capital is concentrated in too few lumps that are too large, it stops being a force for good, and starts to act as a force of oppression.
Capitalism can work really well- but only if regulated. A modern nation state needs to have robust regulation of capital in order to keep it working for the benefit of society. Unfortunately this doesn't really happen just now in the US- most politicians are to some degree beholden to powerful, private interests who seek to increase their power by favourable legislation that generally involves financial deregulation.
An 'illuminati' totally engineers the US economy by lobbying politicians, and this is no great secret.
