People, people, people... if the breeders had to feed and house those 2 years old for 2 more years before starting them, they would go broke. And we all know that it's all about the money. Horses in the racing industry are a commodity. If they aren't running, they are costing money. They are like food products. Get them on the shelf, make your profit, and when they expire, throw them away and take the tax write off.
It's important that we, as horse lovers, let everyone we know what goes on. When I tell my non-horse friends about the way race horses are treated, they think twice about going to the races. The general public sees the big name, high- end race horses on TV and thinks that all race horses are treated like that. They don't see the broken down, abandoned, starved, throw aways that are the majority of the industry. We need to take it upon ourselves to educate the public, because we are the public. If racing attendance were to go down, the industry would be forced to change.
