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.
