Also, just because the job market is hot doesn't mean there aren't TONS of chumps. The number of people out there who are happy being underpaid because of inertia far, far exceeds the number of people who will actively leave a job for another to get a bigger pay day. Companies are caught because if they give the subset who are actively dissatisfied a raise, they are giving the "inert employees" a raise as well. Hence they have a huge disincentive to give anyone a raise.
