Indeed it is a warning of the New Deal and a condemnation of FDR-era policies and where she saw America going. Since that was wrong, I guess they want to update it. V for Vendetta went from being a graphic novel about the perceived fascism of Thatcher England in the mid-'80s to being an attack on neoconservatism and where the Wachowski Brothers saw Bush taking the US in 2006 America. However, the fans, not to mention Alan Moore, hated the movie for that (while I thought it was quite good).
But as Rand's worldview was so based on what she saw in Soviet Russia and her thoughts on American liberalism of the mid-20th century that it is a bit odd to uproot it like this. Then again, Watchmen remained a 1980s nihilistic vision of the world and that movie did bad business. Yet again, this "Atlas Shrugged" looks like it was produced by ABC Family, so that can't be helped, I suppose.
