You're missing the point. They don't think about how to maximise profit. They think about how to hit their sales target, how to run successful marketing and how to perform their accounting function.

Assuming they even do that. Their daily thoughts are more likely to be : How can I make sure my superiors notice I perform my role. How can I make sure I don't fuck this up. What do I need to do to get a promotion. I don't feel fulfilled, I think I'll go find a job elsewhere, I wonder where I should start looking. etc. etc.

When you posted these comments were you thinking : how does posting on HN maximise my profit ?

Let's not forget about human resources: filled with people whose only job is to think how to make more money for the company by spending less on employees.
