Articles like this are important. These issues need to be kept in the public eye. 
Overcrowding and understaffing of hospitals affects public health, not jus individuals. Sitting in an emergency waiting room for hours, surrounded by coughing, vomiting, incontinent people is a great way to catch a disease while waiting for the 10 stitches you need.

The trauma of being abandoned in a hallway can't be overstated, either.  Lying in pain, trying not to fall asleep in case there's a thief just waiting to acquire a new cell phone, or wallet or even wedding ring; being bumped by everyone walking by - the noise, the lights, the feeling of anxiety and uncertainty while being ignored by the 'health professionals' who are totally overwhelmed and just racing to catch up.
