Well, you don't think the society benefits from the companies? Where else would you get all the stuff we use for everything? Where do you get the factories? Where do you get the machines? Where do you get the software?
If you don't think companies bring societal value, ask yourself what the alternatives are. There were a bunch of attempts in the 20th century, however it never ended good for the population.
Society overall gets varying amounts of utility from companies. Mostly they exist to help their owners harness the wealth creating power of workers. By some methods of accounting, many of them are a drain on society; they centralize wealth and create much bigger external costs (resource depletion, pollution) than they create value (engineered obsolescence, disposable crap, useless products & services or ones that serve artificially created demand)
Car dealers, patent trolls, for-profit health insurers, security-theatrics firms, content-distribution conglomerates (ISPs in the US) all are exploiting regulation or lack thereof to profit at societies expense. A lot of finance industry behavior is about unproductively extracting money from other participants. (for example 401k holders)
It's my opinion we should aggressively curb all counterproductive business models, but they tend to be good at protecting themselves. They either win over the masses through PR and deceit, or use more direct corruption of regulators.
I said "companies of a certain size". Don't make this into a socialism vs capitalism issue. Yes, companies benefit society. But I believe trillion dollar companies are a negative for society. They get way too powerful.
Same with governments and the attempts at state capitalism you're referring to. Everything always is good unless it's bad, the question is how easily can it be constrained when it goes bad (and monitored for the signs of it going bad).
