I learned a long time ago not to let ‘this’ bother me. As I’ve mentioned in numerous threads, I start and back my own. Some I’ve bred (backed and started the parents too) and many I acquired from the breeders as unbacked youngstock. I’m an amateur, not a professional. I earn my keep and pay for the horses in another way. Riding, Training and Showing are all my HOBBY. I am addicted to the whole horse thing. I would never, ever, ever want to turn my hobby into my ‘living’. That would be the surest way to suck all the pleasure out of it. People who see me with my horses and on my horses know that I can ride. They know that I didn’t buy it. Maybe it’s because my mounts are all unconventional types or maybe it’s because they know I simply don’t ‘have the money’.
I know that my medals (bronze and silver so far) were earned on horses I brought from the ground up on my own and that’s enough for me. I’m proud of my efforts and grateful for those mounts who gave me the gift of the relationship I was allowed to develop in order to get there. For me that’s more important. My medals of distinction come from seeing others earn their medals on horses I developed, not to take away from the riders’ accomplishments because they didn’t exactly buy the medal ‘from me’ and I know that each ‘ride/mount’ required a certain skill to be able to go in and navigate the tests successfully. I also earn my medal of distinction each time a BNT gets on one of mine that I’ve trained or coaches me and confirms that the basics are there. Again, that means more than another plaque, certificate or name in an annual ‘rag’…case in point, I was entering an arena to school the day before I was to show in it. A trainer was schooling her student in the same arena. We were to ride in the same test the next day. The student didn’t have any idea who I was and from my perspective there wasn’t any reason for her to know. Evidently she must have made a somewhat negative or derogatory comment about my pony steed and I…to which the trainer said, “Don’t count her out, I’ve seen her come out of nowhere and steal the class.” LOL…again, THAT tells me that somewhere I already carry a medal of distinction 
If they gave you medals each time you brought a horse through the levels I’d have more than one bronze and silver…no need for distinction. I am one of those that eeked by in the low 60s at PSG to earn my silver, though I did manage more than a few scores in the high 60s through 4th level; so, take my perspective with a grain of salt. Maybe medals of distinction would change my view of a trainer; but, honestly it would impress me more to know that a trainer can both produce both horses (with their arse in the saddle) AND students (without the need to put their arse in the saddle).
