My dad is a lifetime chewing tobacco user, he had no issue and didn't cost much. He says he's better insured now than at any point in his life.
No system is perfect, but ours is better than most. And again, there are no shortage of programs to help people who are in need. If you aren't aware of them, you either are not in need or just haven't actually looked. With my daughter, I've certainly racked up the medical bills, but not more than we could afford as we paid them off with no issue. We make to much to qualify for any of the programs that help, but those that do, they get the exact same care and it's all free and many do qualify. Programs are out there if you look for pretty much everything.
Lack of healthcare in this country isn't a reality, it's only a political bullet point for idiots that will believe it.
Maybe you should log off the internet and get outside. You are incredibly negative, doom and gloom, it's not healthy.
