Not so fast. You don’t get to paraphrase for your ideological comrade. So lets look at his exact statement.
“Under government healthcare, the expensive old man who no longer adds value to the society is simply allowed to die by attrition.”
In his example, he cites the expense of caring for the man and he cites that the man dies “by attrition”.
Refusing care because it’s expensive is euthanasia if the care is reasonably demonstrated to work.
As an aside: If it’s not reasonably demonstrated to treat the disease, then insurance - both government and private alike - is not going to approve payment for the care, particularly if it’s expensive.
Neglect and deliberately refusing care on the basis of cost are not the same thing and shame on the liar that presents them as such.
