I'm sorry my good sir, but I seem to have missed something you consider to be important. Why shouldn't I be willing to sacrifice myself to save others? Is it suicide that bothers you - would it be different if I worked in a hazardous environment or went on a one-way research mission to Mars?
Yes, I have to say someone who would equate the value of their existence into money as someone I have serious issues if they are discussing public policy. If that is your perspective on the value of something I feel is most precious, you may have other ideas that would have a core fundamental assumption that life does have a price and with that, make some choices easier.
If you support Social Security and Medicare and the policies surrounding those programs (such as whether to raise the associated taxes or change how much they pay out), then you are supporting equating someone's existence into money.
