The Way we speak

So I Googled well-known and inspirational speakers just to be sure I haven't forgotten anybody and I found something interesting. I found that the top 100 inspirational speeches were all given by either presidents, vice presidents, or other highly influential political people. I find it completely entertaining that according to American Rhetoric the top 100 speeches are all political. I am not a very political person, and I would rather do just about anything instead of listening to a political speech. According to the Premiere Speakers Bureau, the top 10 famous speakers are all "famous" people who speak about either fitness, health related success, or making money. Why is it that when I went to look for and inspirational speaker or at least a speaker who does not put me to sleep, I find speakers who want to tell me how to "better myself", "make money", or "get healthy"? Are there no speakers who, want to tell the truth, and entertain at the same time? Honestly, the speakers that I like, are the ones who tell things like they are, and don't use a lot of  large words, I would require a dictionary to understand. I don't know if he would be considered a well-known speaker, but I really like to listen to poetry by Taylor Mali. He is an elementary school teacher, who does poetry. He tells his stories, and at the very least appears to be honest.  Yes, he is on the better side of the cuteness scale, but his tone of voice is what hooks me.  Most of his poetry is about teaching, so the fact that he is a teacher gives him that credibility. Mostly what I like is his way to grab the audience and make us all feel like we are parents of his students, or teachers in the break room chattin' it up, and he is telling it like it is! To me his Ethos is his honesty.
