I'm not convinced it's that broken, though - at least from the recruiter's perspective. I have no doubt they pick up many candidates - those of us that are more "discerning" as just the collateral damage.
I'm thinking that recruiter's being able to pick up large amounts of candidates doesn't necessarily equal success. Success would be defined as companies getting the right fit for their job openings.
Simply filling those job openings every time does not mean the right fit is found every time.
