Not to sound cold hearted or anything, but that depends entirely on the price of the saw, the frequency of saw related accidents, and the cost of health care/legal battles.
Now, if I were a business owner that used a table saw I'd think hard about this. It would be very damaging to business if someone had an accident. For the morale of the employees, the cost of insurance, and the personal piece of mind, I think it would be tempting even at a high price.
But there has to be a price. You can't just say "fingers are priceless" and be done with it.
