Employees' experience is valuable, but not more so than talent and drive
The underlying mentality is hard to argue with. Most employers looking to fill a vacancy don't have the time or wherewithal to train a novice to handle the job, particularly for skilled trade positions. If you need a drywaller, you can't very well take people off the street who never have erected a wall in their lives and expect them to operate one in a productive and safe manner without months, if not years, of at least on-the-job training.
