"Maybe I ought to assign someone to the store, make life interesting for your boss." (2.24)
Much of Archie's power comes from his ability to devise schemes and his lack of fear. If he wants to torment Obie's boss, he'll think of a way. Threatening to do so, is his way of keeping power over Obie.

He shivered with dread, realizing how awesome Archie's power really was. (2.27)
If Obie wasn't so in awe of Archie, Archie wouldn't have so much power over him. Obie doesn't realize that his own perceptions of Archie contribute greatly to Archie's power.

The Vigils kept things under control. Without The Vigils, Trinity might have been torn apart like other schools had been, by demonstrations, protests, all that crap. (4.23)
The school uses The Vigils to disempower students, to keep them from organizing and possibly drawing public attention to the nasty things going on there. As such, students are stopped from being able to make positive changes to their school environment.
