Or to put it briefly: You've got a high level of immature, frightened, paranoid, poverty-stricken, unemployed, drug-using or drug-dealing, and otherwise very stressed-out people in the USA....and THAT is the essential problem. It's a society that is sick at many levels.

To deal with it effectively will require dealing with a great many more social issues than just the issue of gun ownership. People need jobs. They need affordable health care (like in Canada and most of western Europe). They need better education. They need a more honest government. They need saner drug laws. They need a government that doesn't keep taking them to war in other countries. They need better public services (socialism!!!).

Try that for a decade or so instead, and see if you have less trouble with gun violence after that.
