With regard to Ms Rowling I am reminded of something Gore Vidal said about the age of great writing requiring an age of great reading. Take away the great readers and you will lose the great writers. They will all be knocking out screenplays instead. Harry Potter, more than any other book, turned and continues to turn on a whole generation of children onto the act of reading for pleasure. If this only becomes a lifetime habit for a fraction of her audience then JK Rowling has performed an immesurable service for a legion of writers and has helped kick up the national average IQ by half a click.
I don't think the Bush administration put getting the kids to read too high on the agenda list. "Leave No Child Behind" pretty much has succeeded by lowering the standards to advance.
Let the people get their information from a minimum of controlled sources and keep them in line (i.e. fearful and ignorant).
