Another situation to demonstrate that money spent on a thing does not accurately indicate your value of the thing that money was spent on.
It is a long-held position in my family that if any of our pets get cancer we won't subject them to chemo treatments and surgery. They can't consent to it, they don't understand it; all it does is prolong their life for a few months or a year, during which they feel terrible the whole time, all so that we don't have to say goodbye to them sooner rather than later. We would rather do what we can to make them comfortable (a decidedly less expensive option than chemo and surgery), rather than prolong their suffering.
