Could the combination of Alzheimer's and the American healthcare system be any worse?

Dad was diagnosed 10 years ago and Mom has been his primary caregiver. He recently fell, spent just under a week in the hospital, and is now in rehab for the 20 days that Medicare will pay for. The rehab facility is like an insane asylum, but it was the only place with space available. They did everything they were supposed to do -worked hard all of their lives, raised a family, sent the kids to college, saved for retirement. And at $7000/month for memory care, it will all be done in a matter of months so that Mom can apply for Medicaid and lose everything.

Why do Americans tolerate this broken healthcare system?
