[Witcher] Why don't more witchers quit?

Witchers are extremely skilled and well-equipped fighters against either monsters _or_ men. They would make excellent shock troopers, bodyguards, or assassins, and would be worth their weight in gold as mercenaries.

But it's mentioned that most witchers are desperately trying to hunt down what few monsters are left, and end their days alone in some swamp, killed by drowners.

So... why don't more of them find other careers? Not all of them seem to enjoy monster hunting, or at least see it as a viable way to make a living, but the only witchers we see who've gone into other work are the kingslayers.

They may *pretend* to hate it, like SWAT team members complaining about their jobs, but that career is what they've been indoctrinated into and is the top of the heap.  

When it comes down to it, if you've made it that far through all the weeding out, nothing else would ever feel right.  The power and respect and feeling of satisfaction of being one of the handful who can actually do what you do.
