The way I've heard it, patent examiners must meet high quotas. Rejecting too many applications and fighting the inevitable appeals (which isn't counted equally as useful work for some reason, possibly because it doesn't bring USPTO very much revenue) can cost them their jobs, while there are basically no consequences (at least not for themselves or USPTO) for rubber-stamping applications that should rightfully be rejected. If your prior art can only be seriously considered one time, that's not who you want doing it, however qualified they might be.
