I would contend that even saying "a lot" is going overboard. Don't you think that those people who are "business people" are probably there because they know something that comes from their educational background? Just because you sit in a cushy office telling people what to do and going to meetings doesn't mean that you're no longer involved in what happens in a company as far as the actual work. Most "business people", as you call them, usually have some kind of background knowledge into what they deal with on a daily basis. And most of them have a degree in a similar field.
