Not sure which part of the country you’re in, but saddleseat is booming in my area (Midwest) with prices comparable to dressage. $50k+ for a horse, leases starting at $1k/month (just for the horse), and a nice funnel system with well run Academy programs and camps (unlike dressage).
The coats are eye opening. I can’t imagine spending $3k+ on a beautiful coat that I’ll wear for one season, or even one show, knowing I’ll have to do it again and again. Sometimes multiple coats for one show. The shoeing packages are another regular big spend.
It really doesn’t matter in the end. If one thinks they’re saving money somewhere, it’s just spent in another area. I’ve known trail riders who spent $100k on their dream LQ trailer so they and their $500 kill pen rescues could have all the creature comforts not typically found at a campsite.
