Yes, but Trade, where else are the "culture" and economic system so much better? Are there no people being left out and marginalized in other countries? Of course, there are many things about this country that are not perfect, but that theory is too over-generalized.
The variable is easy access to guns. That's the only variable that makes sense. Without that, the "left out and marginalized" people would not be able to enter crowded spaces and kill multiple people, and terrify hundreds of others, within a minute or two.
