I never even mentioned economics, thus your comment does not in any way disprove anything I said.
In your example, the employer buys time, not information. Time is significantly harder to reproduce or copy than information is.
So, one way to charge for information is to sell time sensitive information (like stock information), but then what you're really selling is time exclusivity.
Selling information without any kind of unique or time sensitive properties is doomed to fail — the only thing that made it once possible was technical limitations; information needed for instance paper as a vehicle to distribute it. Those technical limitations are gone now.
