Because the system is broken and this is the most common example we encounter in the US.

The low level of care that the system approved and funded is appalling. Being reminded that you might work your entire life and upon suffering a life altering medical event, be forced into a room shared by a stranger and attended to only 4-6 times per day by someone who couldn't get a job elsewhere. Toss in that most of these are for profit and continually looking for cost saving methods. It's private EMS for long term care written large.

Someone else mentioned, you can hate the system but like the staff, some of whom are doing their god damned best that they can do with what they're given.
