Why is nobody addressing the mental health problem in America?

This may be relevant in other countries as well... But in the past few decades, mass shootings, suicide, overdoses, murder, hate crimes, etcetera. Have all been increasing drastically in frequency and severity. The attention is all getting placed on gun control, when it should be placed on mental health and parenting. Why are so many more violent people being born now than before? In my opinion people that are capable of these acts have lost their humanity. I think we should be fighting against mental health and irresponsible parents, not guns.
