Optics are a big part of the problem. We have job boards all over; here, SO, 37signals, etc... Everyone makes their own job board and wants $500 for employers to post there. So instead of giving gobs of money to the individual who successfully gets you a candidate, employers have to hand over gobs of money to feature their job on these boards (NumBoards x $500). Seems more like a human problem where fixing the optics of payment on successful completion changes to something that better gauges quality.
