No, these are clearly laudable and universal traits with which liberals take no issue; rather, its the vilification of the working class and government as the mob, the dissonance created between the middle class and a perceived elite entitled to privilege and power that liberals correctly object to.It is symptomatic of Liberals that they find these thoughts to be reprehensible.
There is no privilege assigned by any exterior power to the elite in the Fountainhead or Atlas Shrugged. The only privilege reserved to the elite is that they be allowed to work as they wish, when they wish on what they wish. This is a fiercely internal and individual thing and is not "gifted to them by any authority.
The vilification of the mob is not a vilification of the working class but is a condemnation of the vile snakes in politics or opinion formation that pervert the system for their own gain.
Rand correctly and accurately states that there are those who are by virtue of their native intellect, talent, skills or abilities better at doing some things than are most. This is something that is so evident, I don't think it can be argued. Rand further states that the talented are the critical success producers of society and that without them, society is less able to achieve.
The perception of someone being elite can be real or can be an illusion.
The singer, Tiny Tim, and the physicist, albert Einstein, are two that gained elite status within society. One was actually great and the other, not so much.
Rand argues that removing the those who are actually great from society leaves us with the pretenders and the cost to society is great if this removal proceeds.
Liberals attack those who rise to elite status as undeserving and demand that the elite "give back" or "pay their fair share". Rand's belief is that by simply plying their talents, they serve society and society benefits greatly. Without the exploitation of their talents, society suffers.
The "Power" of the elite in the world of Rand's books is only that they do what they love to do and not be constrained by those who seek to pervert the talents and skills of those, like Einstein, who are actually the elite.
Einstein, incidentally, is a perfect example of this as his work enabled the Atomic Bomb and his belief system did not directly endorse the creation of the bomb. If it had to be created, though, he was certain that the Nazis would be the wrong group to possess it unilaterally.
You seem to have completely missed the point and the meaning of what Rand wrote.
