Regarding the post made by the OP, I have found that to be that case not just with aviation jobs, but just jobs in general! For instance, just about any job I have seen posted or read about requires "2-3 years experience in XYZ" or "at least 5 years experience in ABC." It seems just about anywhere there are no entry-level jobs. And those entry level jobs really can't be used to get next-level jobs.
