She no doubt placed people of high ability on a pedestal but she in no way thought they should be able to force other people into doing their bidding. They only "lead" by virtue of their competence and your willingness to accept their paycheck. There is a world of difference between your boss at work telling you to do something and a dictator of a nation giving you orders. (Your boss can't have you shot for example)
I'm not so sure this is a fair analogy; because according to Rand my boss would be just another riffraff like myself, oozing with inherent depravity and in need of a real leader, (like herself).
Not true at all. She certainly did believe that the great could and should dominate lesser beings. Again, her Fountainhead hero burns down a building (with no thought of nightwatchmen) because its banality offends him. Never mind, of course, that the protagonist rapes one of his early rivals!
