Yes, but there are other byproducts besides mere meat. Offal for pet food, glue, bone meal, hides, whatnot. That's true of cows, too, but there's a lot more regulation and care in processing a cow for the table than for horse byproducts, which affects the cash supermarket price for beef. So, take the $800 with a grain of salt if you want to. I was going by what I heard anyhow and I wasn't as deaf then as I am now.
I know there was a flap (maybe still is) about the roundups of wild horses for the export meat market. I chuckle to think that maybe some of the horsemeat noted in the OP came from America's Bureau of Land Management land.
Heh.
