I get you but its not like its either or. If anything statistics about euthanasia would at least be an argument that social programs are insufficient. Sorta the ultimate weigh. If all places allowed it, it would likely be a pretty obvious metric for quality of life. You could not get it to zero but it would be obvious what places are not even trying. Come to think of it its obvious now why many politicians do not want to see that right be a thing.
