Didn't mean to imply that you were dumb at all, most people with age I guess just have a little more cynical view of life, sorry if you misunderstood.
I may be totally off base here, but I would say most top end race horses are treated better than many people's children, most are also never seen by the owners. Most race horses are strictly an investment for the owners, that's just a fact of life, they have a stable hand, trainer, and a whole list of others on staff that are responsible for the care of said horse and if I had a potential of millions in an investment you can bet they are getting the best of care.
As you stated, my cattle are an investment you are correct, and when they don't perform they are sent to slaughter, what do you do with yours?
