Scientists like Carl Sagan, Stephen Hawking, and Neil deGrasse Tyson have done more for the public interest of science than any so called administrator, and oddly enough they tend not to impose their specific agendas in the process. If the "public" realized how much money goes into science vs how much money goes into the private military industrial complex they would be appalled. Or, perhaps the public is apathetic and "public interest" is merely a scape goat for the media. Someone, after all, must tell the public what they are interested in.
