You also don't know what you're talking about. USATF is indeed made up largely of volunteers, but the budgets, whether the local Associations or the committees at the National level are set up to help cover some but not necessarily all expenses (ex. attending National meeting, acting as a liaison/official at Championship events).
The volunteers come from all different expertise backgrounds, and most have been involved with the process for a very long time. If they were in it for an ulterior motive, they likely wouldn't be involved for long. Some may have served through the decision making of past Olympic Trials, and then the Olympic Trials themself (good or bad). Where was Max during past Olympic Marathon Trials? Was he getting ground feedback from the athletes? Does he understand conditions, courses, and timing of an event and how that impacts the ultimate outcome (performance)? Does he understand relationships and experience of a race? If he's just looking at from a business background, that's being highly shortsighted and ignoring a ton of other variables, which is where the committee members come into play.
By the way, were YOU at the National meeting? The biggest people with egos were Max and Stephanie. Max intentionally put people up to speak about how great he is.
