I also think it's also a mistake to compare a corporation to a person. If you never worked with a large group of people, you may not appreciate what kind of issues come up when things scale large.
However, you can even begin to see the issues if you try to manage a group of just a couple dozen individuals. When you hit groups of a thousand or more, management of all the unintended effects becomes a huge job - one that no corporation has been on top of, IMO.
As is often mentioned here, the mandate for a public corporation to make quarterly profits for stockholders is a source of trouble for ANY public company. There is "evil" in that structure itself, it seems to me.
However, the reason I wrote this post was to point out what our job is, as SEO practitioners. We can't do what we can't do - for example, we can't change the way corporate law is written in time to save our own businesses. So we need to know what areas to chill about so our heads are clear and we actually CAN work our own businesses with some clarity of mind.
