From his experience, what he said probably makes sense. Many larger corporations have weighted scales and schedules in place regarding pay raises. You don't get one, or even extra consideration, just because you ask. They're based on milestones. Continuously asking for a raise can be a negative mark for you with supervisors--I know because I've been there. I've been annoyed by a relatively undeserving employee asking for a raise often, to the point they tried to turn it into a running joke with a "just kidding" on the end.
It's funny to me that he isn't allowed to give honest advice which might actually be helpful without people being offended. That's dumb. People might not agree, which is fine, but being offended? Give me a break.
