In response to the vet portion of the equation...

Like a farmer, who must weigh and consider the cost of keeping livestock, sometimes it is not a prudent business decision to spend a lot of money on a vet. This, of course, depends on the animal. If its a high end animal, then it may be warranted, while alternatively, if its a low end animal, it makes no business sense to hang yourself with an overinflated vet bill.

In other words, the value of the animal has to justify the cost of the vet.
