Poor people walking around with untreated TB is an even better example. Treat them for a few hundred a year or treat the dozens of people they pass it on to. Maybe they even give it to YOU or a family member. All it takes is walking down the street near them when they cough.

There is a whole bunch of contagious diseases we should vaccinate everybody we can as a public health effort. Likewise, there are a whole bunch of preventive things we should do on everybody (like breast cancer screening and colon cancer checks) because when you wait until they are advanced, treatment can be very costly and less successful.

Purely from an economic viewpoint, if you are not going to let people die untreated you might as well go with the care delivery system that is cheapest. Republican health care plans all ignore this simple bottom line for ideological reasons. Republican Health Care is too expensive!
