In my opinion, Ayn's work is a welcome aid to the ultra-wealthy who pretend to the world that they have earned what they have acquired.
The ultra-wealthy have leveraged political will to create a Flood Up Economy that automatically becomes a Feudal system of Corporate Serfdom with perceptible alacrity, they have misnamed that economic model a "Trickle Down Economy," they have deliberately conflated the terms "earning" and "income" in common usage in our language, and they now argue that everyone should be able to "keep what they earn," by which they mean, everyone should be able to keep their income whether or not they have earned it.
There is no single human on the face of planet earth that earns $1,000,000 in a single year from their work product. That person does not exist.
There are many humans who have annual incomes far in excess of $1,000,000.
Ayn focuses on the character of Galt, a working stiff, who succeeds through access to a quality education, personal innovation, personal ingenuity, a desire to better humanity, and thousands of working stiffs, much like his father, hired as laborers to manufacture his inventions, without whom, his innovations and ingenuity would be just shy of worthless, if not never sold.
I found Atlas Shrugged to be offensive to the idea of rational ethics in its myopic perspectives on personal worth.
It advances the false, ethically reprehensible idea that it does not matter how or why someone has achieved success, only whether they have done so. Galt does not care what would happen to other humans as a result of his professed "Objectivism" which is actually only a piss-poor mask for selfish vanity. He lacks the perspective required for valid Objectivism, as does every human.
It's an exceptional and indelicate conceit Rand offered, pretty to look at only until it becomes reality.
Paul Ryan is a huge fan. Really. He considers Rand's work to be a very significant influence in his life. I don't consider that a positive endorsement, but do consider that support for my perspective that Ayn has offered base conceit and vanity and gave it a lofty sounding name.
