It was predicted, but has been followed up on now:
The study -- which focused on uninsured people in Richmond, Virginia who fell 200 percent below the poverty line -- found that over three years, health care costs fell by almost 50 percent per participant, from $8,899 in the first year to $4,569 in the third after they received insurance. Participants who enrolled in health coverage made fewer trips to the emergency room, which are notorious for running up patient bills. Instead, insured participants went for more primary care visits.
I'm happy to see this, too.
Or, maybe we could put some type of universal healthcare system in place that isn't just for low income families.
