These cases are always sad individually, but collectively they would all bankrupt the system. Even private insurance has caps on it for lifetime expenditures in nearly every policy.
I rented to a woman who was getting free cancer treatment and surgery; some sort of government assistance. She literally smoked and sipped beer every waking moment. I was over there once really early to fix a leak. She had staged a beer and cigarette next to the toilet and lit and popped the beer the moment she got up. When she moved out, with months of unpaid rent, she left $100 worth of EBT card steaks in the refrigerator with the power off for two weeks. She did take all the beer.
Why were the taxpayers paying for her to eat steak and get free medical when she couldnt be bothered to quit smoking and drinking? How did this woman with all her medical problems afford an awesome quantity of beer and cigarettes daily? Were it not for the taxpayer she might have been forced to make real world economic decisions like buying food instead of beer and cigarettes. Giving up those two things would have done more for her health than any medical care.
