This was... many hours of my life that I won't get back. 
It was ok at the beginning and got steadily less interesting. Dagny is ok but most of the characters are somewhere between annoying and awfully unlikeable. Around the halfway point, I was done with the story altogether. I found myself just increasingly frustrated with the author's filibuster-style speeches. This story could have been told in probably less than 10% of the words, without missing anything. But honestly I think the "story" of it is just an excuse for a very long-winded monologue by the author on how they believe society, and individuals, should behave politically and morally. 
The plot is so boring and repetitive that the character monologues were almost easier listening than the events. Why does it just keep going? And going and going??

The book is pro-capitalist, but it might be better described as anti-[anything but extreme capitalism]. The author is clearly so elitist that they seem to truly believe that blue collar workers do not have brains. The idea that "men of the mind" are greater, and even more truly human, than the rest of the population comes up over and over again. I don't have a problem with capitalism- I reside in a capitalist country and I can see both pros and cons to it. But I have a pretty big problem when it is said that public welfare is welfare of the undeserving. 
Obviously I am aware that this is a work of fiction but when every character has the exact same worldview and finds a reason to get on a soapbox about production vs entitlement, it's safe to assume the author holds that point of view as well. 
By the time I got to Galt's radio sermon, I was convinced that the author felt themselves a second Jesus, tasked with preaching a new way that contradicts everything Jesus taught. Help less fortunate? No way, every man for himself. Contribute to your community and work at keeping peace? No way! Because obviously the only way to be happy is to get ahead of everyone else with your (morally required) hard work. Humans don't have value unless they are leaders in their respective industries, silly. And if a human isn't living up to a "full potential" then that life definitely is not worth anything.
The idea that the rich ceo's are being taken advantage of by the system, and the whole arc of a bunch of them going on strike and living off grid to teach the lowly employees a lesson on how they couldn't make it without the smart inventors and managers giving them instruction... I can't. I just cannot. 

I can't believe I kept listening to this but I was so determined to finish it. I'm so glad it's over. Would not recommend. Honestly the worst thing is that I know people who would love this, be entertained, and agree with a lot of it.
