My business has overwhelmingly gone after young workers who we can shape to the position, rather than more experienced workers who have skills that supposedly match the job description. Obviously this wouldn't be the case in some fields, but we've found that personality and the ability to learn effectively far outstrips current knowledge base, probably because a large amount of what is taught in school is practically useless in the field.
Due to this focus on younger workers, we now have a highly motivated, highly specialized workforce and don't have to deal with employees with big egos who think know the "right" way to do a job.
