I consider the welfare of the horses more important than money.
Mite explain why I am beatnik poor, too.
But I like myself, and our horses will never hafta worry about that.
It is what is important to you. Money is just a means to an end for me, but my heart wouldn't let me sell a horse for slaughter when I knew it was only 'dangerous' because some human screwed the horse up.
You can still make money offa livestock and still have all consideration for your animals. I know of a menonite guy near me that has dairy cattle (and some horses). He took a cow to slaughter recently, but he was devastated about it. (Cow had a septic leg wound, wasn't getting better and he can't use medicines that aren't to be used on food animals.) He had no choice, and slaughter was a last option for a suffering animal.
A dangerous one is one that was incorrectly trained and handled, (we aren't talking about one injured beyond hope of recovery) and reguardless of money or whatever, it is WRONG to have the horse killed when it was the fault of a human that he/she was like that anyway. There are other options, but it seems it is about MONEY and not HORSES. If you REALLY care about the horses, the money shuddn't matter.
If you are into horses strictly for money, you mite be in the wrong business. I am in it for love of the animal, and that love overshadows my greed for money.
Edited to add... I myself cudda made horses my trade, I cudda got into training and breeding for money, but in order to REALLY make the money, I would have had to sacrifice my morals, and what I feel to be right with horses, so I chose to go into nursing. THEN I don't hafta compromise, I don't hafta do what I know is wrong just so I can make some bucks......
