Mental Health in the U.S.

Maybe some one can explain to me how that in the supposed greatest country in human written history, can be such a failure when it comes to mental health care? We supposedly have the best health care in the world, but that has not been proven to me sufficiently, yet. However, in New York we have aparently a woman dying on the floor of the ER in front of everyone with no one paying even the least bit that she was there. When will we wake up to the real need of decent care for the mentally ill in America? Do not even get me started on what is happening to the rest of us.
