Sounds to me like a very jealous OP ;)
I have two definitely not $500 horses. And I love them dearly. They are NOT performance machines. My youngster gets so excited when he sees me coming that he starts shaking - if he was a dog, his tail would be wagging madly.
He leaves his food to watch what I'm doing - last night he couldn't quite see around the corner to watch me, so stood up on the ledge of his stable with his front feet, pushed against the door as hard as he could, stuck his top lip out and scrunched his eyes shut to get an extra few cms!
This morning, I found him fast asleep, sprawled on his side, and spend 10minutes laying with my head against him while he slept.
He definitely didn't cost $500 - buy I can tell you, the amount of work I had to put in to afford him makes me love him and appreciate him even more. I slogged my backside off bigtime to get the money together to pay for him.
I've had my fair share of $500 horses and done well with them too. I always scrimped and saved to afford professional lessons. I am ambitious, I don't want to be a happy hacker. I love dressage, its what I want to do and I want to be as good as I can possibly be. This requires expenses, such as lessons.
There came a time where I realised I was never going to get where I wanted to go, on $500 turn around horses, hence I saved like crazy to afford a double figure horse.
I know have two. I buy my clothes from the op shop most of the time, my car is ancient, my trailer is ancient but safe, my saddle was second hand but I love it and it is of good quality, I do not keep my horses in a top facility - they are at a friend's parent's property close to my home, with basic facilities and a pretty dodgey arena.
But I REALLY want to be the best that I can, and to do that sacrifices need to be made in order to afford a quality horse, and quality instruction.
OP, and anyone else of the same mindset, not everyone who has an expensive horse or trainer is a snobby, 'rich kid' having it all handed to them on a platter. MAYBE, just maybe, that person you are having a go at, worked harder than you've ever worked in your life to achieve what they have.
If you want the same, then you need to pull your finger out and work for it.
