I think that all equestrian competitions that are judged subjectively are inherently susceptible to abuse and corruption. I was once told by a trainer who showed in multiple disciplines that jumpers made the most sense to her because the judging is objective. It’s time against the clock and rails down to calculate the score.
Can you really blame the young riders who grow up admiring the international dressage riders and want to emulate them? How would they know any better? Anyone can get caught up in the normalized behavior of dressage - from the exorbitant prices for competitive horses to the less than kind training techniques. If you need proof, just look at where we are today. It’s not just that there’s something rotten in Denmark. (no pun intended)
Reining is another example of subjectively judged competition where the horses’ welfare is not prioritized. My vet told me that a lot of the reiners in his practice are done by age 6. Six.
Dressage done correctly makes a lot of sense to me. Unfortunately, competitive dressage does not.
