This page would have been from the end of Millar's run on the Authority, during which they exclusively fought (besides the evil Doctor, who had the sort of power level that made money superfluous) villains that were funded by the sort of limitless black ops government funds that inevitably feature in conspiracy theories. This brief mention by Hawksmoor on the very last page of his last issue is Millar making a token effort at throwing in a Big Idea after using his run to feature a number of gross-out scenes (and crying censorship when DC wouldn't run, say, a page that featured Jenny Sparks' counterpart in the fake Authority team about to have sex with her corpse, among other things).
If you want to read a comic that does more than mention class issues in the superhero/supervillain community, you could do worse than to start with the Astro City TPB The Tarnished Angel, about a third-rate, middle-aged supervillain trying to go straight, and some of his similarly second-string-Rogues-Gallery friends and neighbors.
