Earlier quoted context omitted.
Wild animals don't know what they're doing, the people behind corporations do. Corporations are abstract constructs, but they're run by people. And in this case the people are amoral assholes, extortionists leeching off of the work of others.
The people who run corporations have obligations towards their investors. If they disagree, they may quit, but they cannot run a corporation against the interest of its investors. And, if they quit, someone will replace them. This turns corporations into sociopath-like entities.
Okay, then the blame lies with the investors... No matter how you try to view it, in the end there's always people involved. Of course reality is complex and there's always a number of interwoven causes for everything instead of a single determining factor. But, and maybe that's just me, I really don't like this hand-waving of any kind of personal responsibility because "corporations exist to make profit" or similar nonsense. As if that makes it somehow OK.
