It always bugs me when people misdiagnose the cause of a lot of bad behavior by corporations, big ones especially. A lot of heat gets thrown at the corporations, and much is wasted burning the branches of this problem and ignoring the root, that is, the state.
Certainly, corporations can and will try to get away with a lot. But they have very little power to actually push people around before the state gets involved. And the state loves to get involved, because working with corporations gives them an excuse to use their power and find reasons to demand more!
