It's not just the people with lower IQ that loose out. People suffering from mental illness / delusions are drawn further into dysfunctional ways of thinking by the system and media. This group of people are of course both rich and poor.
A raising of conscious awareness in all will create a much more peaceful and harmonious society.
When huge swathes of the population are mentally ill, guns provide the means to turn their inner delusions into an external hell for many.
