Who is John Galt?

For those who don't know the background of this question, I'll explain.

John Galt is the main character in the book "Atlas Shrugged" By Ayn Rand. Through most of the beginning storyline, the supporting characters are all asked, (or ask) the question "Who is John Galt".

John Galt, Is an inventor, who is the antithesis of the establishment. Through the book, his identity is steeped in myth. He is the "Atlas" referred to in "Atlas Shrugged" in that he "holds up the world".

I can't help but mention that he gives a rather lengthy speech in the book, that outlines the ideas of objectivism... which is a philosophical movement.

I don't follow this movement, but Its probably important I mention that before someone freaks out.

My question, "who is John Galt" is different than the one intended in the book. When I ask the question, I mean to ask, who is the puppet master... who is pulling the strings... who is responsible for this myth we know of as "John Galt". Who is the propaganda artist, and to what ends does the artist seek to impress.

Back in the Bush era, most people knew fairly quick that most of the administrations propaganda was being churned out by Carl Rove. It was actually pretty obvious :P Now, we have a new administration now, and a pretty shiny new congress...

Now, as I'm seeing some fairly new and old propaganda techniques surfacing... I ask the question.... Who Is John Galt...

Who is the person giving us these subtle propaganda messages... Who is it that is holding up the world so that it looks just right for us, and satisfy the powers that be?

I don't know. And chances are, we won't know until after the administration leaves office. If anyone out there has any ideas as to who this artist might be... please, don't hesitate!
