Speaking of Dead Horses

I have a link to an expose' on the horse racing industry's waste removal. Everyone wants a great/successful race horse and in order to get it they over breed. Whatever doesn't show promise is sent for slaughter. It costs $60 - $150 to euthanize a horse, and they can get about $300 at slaughter.
I have a couple objections. Actually I have many objections when we talk of horse competitions for $$$$. That in itself leads to overbreeding and flooding the market, necessitating the need for slaughter. They can't all be placed, and not all abused/neglected animals can be saved. This practice is done with all breeds, organizations and backyard pets. Everyone thinks if their horse has the 'parts' it should be bred. Responsible breeding practices with access to 'culls' for pleasure riding placement would be the best solution.
Horse slaughter itself doesn't have to be a horrible demise. However, the enthusiastic efforts of rescue groups have put the cart before the horse so to speak. They have pushed for and won the eradication of all slaughter in the US where they would have had a say in the proceedures. Now all horses bound for slaughter go to Mexico and Canada. Yes the transport/conditions are horrible, but the horse wasn't a backyard pet. It was treated as meat on fast legs and in relation its demise is swift. Some methods are better than others, and some horses can suffer acutely for up to a half hour. Once the horse is gone it is best to use it all, because he gave his all.
So, my objections: Over/irresponsible breeding, and the callous owner who after the horse is deemed non - productive seeks to squeeze out a few more $$ from the horse and sells it for food instead of putting it down or offering to donate the animal.
So, there it is. My opinion. There are 2 videos at this link. If this doesn't work - I can forward the link to you. I had to clean this one up.
