How many children have to die...

...before the system is changed? I was hurt when I thought that the problems were yet to be identified and acknowledged, that maybe people didn't care because they didn't know. Now, I am brokenhearted after learning that the problems have been known, discussed, debated over and over again, year after year, death after death. People know the system is deadly. THE SYSTEM IS DEADLY. Children are dying, and the root cause is known. What is an acceptable number? If one child is just an individual situation, if the aggregate data show that it is more than one child but the issue is not one that is crucial enough or at least not to the powers that be, how many children have to die before the system is actually changed?
