I find some of the most relatable parts of the story to be the vague hero-against-the world / morality allegory, particularly in the dialogue quoted here. I think as much of the micro-morality of the story is Randian in a way that as much of the surface dialogue might paint Rand as a negative colour (if only by showing how ugly her beliefs on the surface, but revealing their purer roots). Harry is basically saying "Yes, everyone is incompetent; woe that they didn't have the luck to be not, and let's try and change that without getting too annoyed". With greater intelligence comes greater ability (and in a sense perceived moral obligation) to restrain or make productive one's hatred towards that which can't be changed or that can't be changed easily. Harry is taking morality as being the extent to which a strength can compensate for weakness in the spirit of creating future strength. The Randian 'strike' is a utilitarian way to achieve Randian values, and not an inherently Randian way or whatever. I don't think it's immediately obvious Harry isn't aiming for Randian values, if perhaps narratively in a way that Ayn Rand would not have imagined - i.e. strength and weakness are much more complexly intertwined.

(It's not obvious either that I'm disagreeing with the parent post.)
