The problem of course is that you don't typically know that it's the last 6 month's of someone's life until they die. So you don't know whether to spend or not.
Another problem is that unless you try, you are never going to get better.
But if you want then vote for death panels that are going to cut your care, because your prognosis is not great, or your older than 50. The Nazi's would be proud.
My father got fungal Meningitis at age 81. He was walking 3 miles a day and working an 8 hour shift as a greeter at Walmart before that. He could feel he was suddenly getting weak, so he went to the doc $ and his blood work checked out. Then he fell in the garden, went back to the doc $ and his blood work checked out. Then he fell in the carport and broke the tip of his tibia leg bone. $$$$. Within a week he couldn't stand even with help. So we took him to the hospital. $$$$$$. He was in the hospital a week before they managed to diagnose him. Then they started the anti-fungal medicine. He had a stroke while they were treating him.
He lived 5 years after that. He didn't walk without assistance again. He didn't work again. But he did get to see his granddaughter graduate high school.
It did cost a lot to give him those last 5 years. But there was no way to know before hand what the cost would be or what the outcome would be. And he had paid for insurance to get medical treatment. And he had also bought long term care insurance to pay for caregivers so that he could stay at home.
They know the odds of survival for just about everything and while I’m pleased your father lived another 5 years, there were probably another 19 that lived less than a handful of months. That’s probably $20 million+ in expense for a few years of life between the 20 total. Fine on your own money, but not taxpayers $. The average person, including their employer portion, only put in about $30-50k into medicare over their lifetime - and that’s for people that actually worked full time 30 to 50 years. A huge portion of the population doesn’t work at all or works for a lot fewer years or has a stay at home spouse. If you want to fund $0.5 to tens of millions of dollars in healthcare costs for a 3% chance to extend life by 2-5 years, more power to you. Just don’t demand that taxpayers do it.
