She is, however, acting in her own rational self-interest by keeping all the value of the new machine for herself and not passing it on to her workers.
No, she rather obviously is not, as vividly illustrated by the fact that she caused so much hostility that she ends up going to the guillotine.
She is very clearly acting in her irrational self- interest.
If she were acting in the group's rational self-interest, she would allow them to work half as long.
And if she were acting in her own rational self-interest, she would do the same, since her well-being (and in fact, as neatly illustrated in the comic, her very life) depends on the well-being of the group.
Since she is acting in her own rational self-interest, she threatens to fire her workers if they do not work the same hours as before and pass the value on to her.
No. Again, she is rather obviously acting in her own irrational self-interest, as vividly illustrated in the last panel.
Any purely rational person (as opposed, mind you, to an empathetic one) would take the option to do that.
What on earth leads you to believe that rationality and empathy are mutually exclusive?
As social animals, empathy is eminently rational, and in fact I would argue that rationality is impossible without it.
No - it's the stance that people who want to self-affirmingly publicly proclaim their hatred of Rand have assigned to proponents of rational self-interest.
That's the heart of my criticism - people don't discuss or debate the idea - they just trip over each other in their rush to be the one to most vividly proclaim their hatred of Rand. Hating Rand is like a hip internet leftist membership badge, so every time her name comes up, everybody who wants to solidify their image as a hip internet leftist rushes in to say, "Hey! Look at me! Look at how much I hate her! That means I'm one of you!"
And since the hatred comes first, everything else is shaped to accommodate it. Like, for instance, misrepresenting the idea of rational self-interest so that it becomes something easily condemned so that it can be added to the list of reasons to hate Rand.
