Speaking from europe where healthcare is basically free.
Medical care for these patients is extremely expensive. Each surgery costs around 50 to 60 thousand euro and it's not uncommon to get 2 or 3 of those before dying. Add to that the frequent visits to the doctor's office, the oxygen tanks if needed, the medications, etc. The other option would be to just "let them die" but that's not what we decided to do as a society.
The trend is that we are now able to keep them alive slightly longer, ( at a higher cost) and that they start developing symptoms slightly later thus reducing the potential "benefit" for society.
