rubbish! This wouldn't (doesn't) work. You end up in the ridiculous situation we are in of having drugs (and people expecting them) that can extend someone's life by two weeks. And for the privilege we the tax payer pays thousands and thousands of pounds.
Unless we are all happy to pay 10% or more tax per year ( and that's just the cancer patients). Let's give all the other diseases every single drug that might extend their life by a few months.
If we are extending these people's lives they will need more hospital beds, hospice beds, nurses, doctors, HCAs, equipment, benefits etc. because they won't be WELL. They are still dying and very sick, we have merely moved the end date further away.
My personal opinion is that many people are already over treated. They receive treatment that ruins the last days of their life and for small gains they often die sick, bald, septic, swollen and weak.
Spend a week in a chemotherapy unit and see how you feel then. Talk to the staff and the patients and their families.
