in this modern day of increased privatized medicine, health insurances and self-absorbed people, what is the incentive to let a person die? the longer you keep someone with medical needs and decent insurance the more you can milk the their insurance or whatever wealth they may have accumulated. self-absorbed closed ones can also easily dismiss the sick person desires and needs. I see no incentive for this to change.
