It's not just the uninsured — it's also the cost of health care

We still have an uninsured problem in the U.S., but we have a far broader health care affordability problem that hits sick people especially hard. Why it matters: It's time to think more broadly about who's having trouble paying for the health care they need. The combination of lack of insurance and affordability affects about a quarter of the non-elderly population at any one time, but almost half of people who are sick.
