I anticipate that USEF will go the way of conformation dog showing.
You will see shows dominated by a handfully of independently wealthy AAs who can travel and trainers who have a seemingly impossible number of horses they are showing. The wealthy but works full time AA with 1-2 horses will be a bit of an anomaly. Politics will increase as a smaller number of trainers occupy a larger portion of the market. Working AAs will be further disenfranchised and less able to take the time off work to campaign a horse. Thus, they will work to make it possible for the trainer to campaign their horses. To make that possible for the trainer, trainers will have more working students. Working students will be from families where they can cover living expenses for “experiential learning” as middle class passionate riders take full time jobs because they cannot afford to be on the road 40 weeks a year with little to no pay. I also wouldn’t be surprised if we slowly saw an influx of Stallions and a movement away from geldings as wealthy owners approach it from more of a business model.
I could also see those wealthy owners who cannot travel bringing out AA horses at the A and B shows that are local and two day. This will further push out the “average AA” on a horse that may have been competitive in 2020. Essentially it will be a continued progression of the pieces already in place. Conformation shows are dying out. It is a graying sport where politics make it very hard for all but the most resilient amateurs to thrive. My crystal ball sees something similar.
