And what do you do when they drink the check and once again lie dying in the street?
I really do agree with you - society can pay up to some point and no more. But at some point people must be allowed to die. For example, today I would not be opposed, in the case of cancer, to society providing payment for all necessary pain medications and hospice care to the point of death rather than paying for (surgery, chemotherapy, radiation) treatment. Lifespans would be shorter, death quicker but it is IMO a reasonable and far less expensive option.
Nobody really survives cancer although they may die trying. We need to terminate the cancer industry (but maintain cancer research). They are an industry selling pure hope with no significant probability of a cure today. They are a cancer on our economy.
