well maybe they should. That's why we have so much reguation. And why instead of following regulation they lobby to remove such restrictions.
Can I really say a company lobbying for worse people/worker/world conditions to be a "success"? The cigarette metaphor is apt here. if you wanna go more extreme, children in mines would be the best success; employees who can't talk back, can be paid peanuts, and are easily replacable is peak success.
