In advanced nations, America is the most violent of them all, of which, no doubt, because the availability of firearms is so prevalent and the usage of these lethal and damaging guns are so frequent, the end result is much more violence, then other comparable countries that have strict or stricter gun control laws. This would seem to indicate that stricter gun laws in America would clearly help to reduce violence in America, which no doubt would be true, but even with these laws successfully applied, America would still be the outlier of comparable countries in violence, for some very basic reasons, as discussed below.
What is absolutely relevant to violence, is the inequality of society within America, in which, Americans readily are aware that there are some people, that have incredible wealth and the material assets and accouterments that go with that, and then there are those others that have absolutely nothing. Further to the point, those that have nothing, see visualize proof, through media of all types, that some of the most successful are, in fact, of the same race or social milieu as they are, which can serve as either a conceivable inspiration for them or as a searing indictment. This, thus means, that those that have nothing, often feel a great deal of shame and humiliation for being nothing, and intuitively know that based on their limited skill set, and the dead-end neighborhood that they live at, that their chance of ever successfully exiting the futility of the situation is well-nigh zero. So then, for those have nothing, and literally have nothing to therefore lose, they are going to be susceptible to desiring to make their mark in a manner in which they will receive some sort of respect and acknowledgment that they are a true force to be reckoned with.
Again, this humiliation and shame, comes about from the recognition that the circumstances that these people live and congregate in, are pretty much hopeless, and thereby the only way to receive some necessary respect from one's peers is to achieve it through the type of action that somehow commands respect, which often comes down not to random acts of kindness, but rather purposeful acts of targeted violence, that demonstrates determined resolve to get things done in a manner in which it will be properly recognized by others of importance, as righteous.
In truth, the people that are most prone to violence are the one and same as those that we judge in a manner, rightly or wrongly, as of being of little value or worth. Further to the point, we do not value and we do respect those that are ill educated, socially maladapted, impoverished, lazy, and shiftless, of which, the most fundamental reason why there are so many in America that are lacking good and proper attributes, comes down to the fact that we have segregated certain portions of our population from the mainstream, and provided these people with little or nary of what they need to become something of value, and then express surprise or are dismayed at the violence so displayed in these neighborhoods, when they strike out in their cry of desperation in the only manner that they know that at least will get some sort of response from a country that has turned all so cold.
