That over 40% of Americans have something that constitutes some sort of pre-existing condition, and that over 130 million Americans live with treatable chronic aliments.
Keep reaching.
It's actually about 45%, and almost all related directly to obesity. If you think it's reasonable that half the country has to pay absurdly high premiums because of poor choices made by others who don't wish a negative cost affiliated with them, I doubt I could say much to convince you otherwise. Rewarding people for their bad behavior is stupid. Poor diet, lack of exercise, and smoking are the three top sources of chronic illness, and yet we make no effort to reduce them, we demand healthy people to pay unreasonable sums so that tubbos can sit in front of a TV eating cheeseburgers, smoking a pack of camel lights and complaining that their preexisting condition shouldn't preclude them from getting health coverage.
I'd tell them to keep reaching, but that would require them to be physically active.
