Of course! It should be co-nspirator, referring to multiple nspirators working together...

I have a feeling it's a little easier to fool Bullitt County than it is to fool LA. After all, they were home to that McDonald's strip search fiasco!

This principle in economics is called market equilibrium. Supply and demand applies kind of oddly to this situation. You would say that the employers are the people who get phished, and that, as you point out, there's a finite amount of money in it. So we have the supply (S) of phishers offering their services, and the demand (D) for said services (D). When S increases, D decreases because, "No thank you; I got phished yesterday." So the average wage per phisher goes down.

But in all seriousness, some of these guys probably make decent money. It's even more difficult than average to claim that you have an accurate picture of the situation, as it's not exactly public information until you catch one of them. A phisher that is. Not a phish.
