I don't think that's accurate; that assumes that 100% of businessmen make 100% of decisions purely to make more money, which I don't think is true. If you have a big pile of money, one of the things you can do with it is buy or start companies that you think will make you more money, but other things you can do include buying/starting companies you think will advance your personal goals, buying companies you'd just like to own, etc.
For example, we have a lot more wealthy tech people owning space-travel companies than I think would be justified based on the economics alone. They consider them valuable to own because they want to own a space-travel company. Similarly, there is some non-zero value, beyond its projected revenues, to owning the New York Times. I would certainly pay a non-zero amount for the social power it would gain me to own the NYT, so there you have an existence proof that the value of its social position is at least a few thousand dollars. :)
