> "Corporations," in this context, is just another way to say people.
No, I think its referring more to the systems that describe how the group of people behave. It is an important distinction.
Also, the idea that effective and lasting change requires significant personal sacrifice and enduring hardship is yet another thing that corporations and politicians would like you to believe. It's great for causing inaction through human nature. Its effectiveness can be seen in anti-riot measures like tear gas or less-certainly-lethal munitions, asking people the question of "do you believe enough to endure THIS?" It's a rhetorical question.
