Lack of community, the break up of the nuclear family (i.e. more single parents=less child supervision), loneliness, mental illness and drug induced mental illness, inadequate access to mental and/or health care, and lack of any unified/mass culture that would set standards for behavior. Go checkout other countries that have a few of those things and you really will not find the rates of gun violence we have. Also, most of the gun crime seems to be black on black crimes, but it's taboo to even bring up racial differences without someone accusing you of being some Charles Murray-esque racist (even if you're just citing publicly available data).
