Why do horses get put down when they break their leg?

When a human or a dog or a cat breaks their leg, they just put it in a cast for a few months, why doesn't this happen with horses? Is it because they are too big to be able to put weight on their leg in the future?

Not a horse owner, but grew up around them:

You can mend a horses leg and keep it alive, but it wont be same. The horse wont run as fast or be as confident. You might not be able to do any jumps or off-the-path walking anymore. Essentially the horse is useless for anything except companionship. You should also know that horses are, in layman terms, fucking expensive.
