I agree with this from the perspective of the candidate. From the perspective of the employer and current employees, picking randomly among a set of 50 candidates (who are all adequate relative the "real world" requirements) trivialises the job and the current staff. Requiring everyone do LC and other tests creates prestige, up-values the current employees, creates camaraderie, loyalty, etc. When there is more than one adequate candidate, the selection process is a ritual that affects mainly the employees. It should be obvious in companies where there is no meaningful payback in a "long tail" of competence.
