@indigomoth - The company can foster competition without making it cutthroat though. I mean, you don't really want your employees driven to the point where they feel the need to break laws.
Look at the demise of some of the media giants in Britain. They must have put huge pressure on their employees if they were willing to go to the point of breaking the law in order to get details on a story.
And not only breaking the law, but also violating what people would consider standard moral values.
Not to mention, as it says in the article, corporations can foster competition but also do things to make you feel secure in your job, like providing child care.
I think if they get the balance right, the behavior of their employees will repay almost anything they can spend on them.
