Mercedes Schneider is a brilliant blogger. She is unpaid. So is Anthony Cody, Peter Greene, Steven Singer, Tom Ultican, and many more. Bloggers speak truth to power.But then there is Peter Cunningham. Once upon a time, he worked at the U.S. Department of Education and was known as Arne Duncan’s “brain.”Now Peter has a blog called Education Post, and unlike the rest of us, he speaks for the billionaires who feel misunderstood and wounded. Hurt, actually, because no one loves them.As Mercedes explains, he is funded by a bevy of billionaires. Gates recently threw in more than his two cents. The billionaires love him. And well they should. So sad to have all that money without anyone listening to you. He provides them a voice on social media.
