Pretty sure the entire point of the post this was clipped from explains that, but again, if you have a job a teenager walking off the street can do with a little training, you have a minimum wage job.
You can dress it up, demand respect for your years of loyal service, pretend you do it better than the new hires (I would argue many do it worse then their energetic young counterparts), etc., but you will still be compensated (both financially and in organizational respect) as an entry level teenager with skills that are easily replaced in the marketplace.
