_Animal Farm_ was taught to me by my capitalist and authoritarian teachers as an anti-communist screed. The problem with the farm is that the pigs end up being capitalists, though I have never seen or heard of the text being taught to children as an anti-capitalist text.
This culture does a very good job of assuming that the field of possibilities can easily and quickly be reduced to two choices and, further, that we're forced to choose between the two and, finally, that anyone who thinks there are additional possible choices is "being childish and unrealistic".
I find the US to be highly authoritarian, full of easy examples double-thought and duck speak.
I don't, however think folks are being manipulated: I think that the fundamental authoritarian move is that folks here have manipulated themselves. To me, that's close to the point of 1984. Or Mark Fisher's books, or Ursula Le Guin. I'm in the middle of Butler's _The Parable of the Sower_ and it's feeling like that self-deception is core to what is happening in that book as well:
folks reducing the world to some pretty horrible binaries and then becoming happily ensnared in the ensuing problems.
