Too many people read too much into "peers". These are your legal peers, not social or educational equivalents. These are fellow citizens. So long as they arent royals, elected officials or cops they are peers. (Lawyers can technically serve on juries but every court i know doesnt want them to do so, nor law students.) We live now in a society with fewer official class systems, or we at least now better separate legal classes, and so easily forget the original intention of such words.
