It's not for a lack of caring, its more usual to do with the fact that a company eventually incorporates. Once this happens, his job literally stops becoming providing a service, but switches to becoming beholden to the shareowners to make more profit above all else, and if not, loose his job.

I think you mean going public. Corporations can be privately held.
