My reading of the lyrics snippet (and I'm certainly no expert in these things) suggests that the character is telling a girl to run away from him because he knows he's a dick. Specifically, he's a dick that's especially good at criticism and spreading negativity and of the list of targets, one group happens to be people who work a lot which implies to me that the character's less-than-hardworking nature looks bad by comparison.
So not only is the character a dick, he's a self-professed underachieving one and perhaps even proud of it. He might even be worried that the girl is one of those kinds of people he hates, or maybe he kinda cares for her and knows his personality is toxic on some level, or he just can't have nice things, or there happens to be a hotter girl one table over so this one has to go...
Anyway, it's just odd because it seems like the character that is "speaking" in the song is exactly the sort of guy who might bitch about how troublesome smart people are because he's always got to be the smartest guy in the room but refuses to put in the work required to remain the smartest guy in the room when there's other actual smart guys in the room. So the best solution in that case is to get rid of the others by telling them to "run away as fast as you can."
In summary, it seems to me like the lyrics are actually speaking more as a person who hates over-achievers and/or smart people than as a person who is one of those troublesome smart persons who hates average folk and therefore would appear to, well, not really support the author's actual argument. Or something?
I don't know. I'm probably not one of the smart ones. so... :P
