You clearly haven't spent a lot of time in the horse business. My father and my grandfather on my mothers side were both horse trainers. I grew up around horses. Its not as easy as giving them away, selling or donating them. First of all it costs a hell of a lot of money to feed and care for a horse. If you are in the horrible position of not being able to care for your horse you can certainly give it away, sell it cheap or donate it. Guess what happens to most horses that are sold cheap, donated or given away. The kind person who took your horse in puts it on a truck and sells it for dog food. You can make a decent amount of money at this and so it draws in all kinds of folks, especially when the economy is tough. I would much rather have a horse killed then starve to death.
