America stopped investing in young men. We talk ad nauseum about how black boys dont have any purpose and wind up in hood shyt The truth is the same thing is happening to white kids too. These boys are growing up in a world where there is no hope for the future due to late stage capitalism, rampant climate change and insurmountable wealth gap.
They grow up with little to no direction and were not socialized to have the tools to navigate adulthood. Remember women have been told for 60 years to go and get it themselves and that they dont need a man. Boys have not been told that and thus are ill prepared for the modern world (The book "Of Boys and Men" goes into this at length). This results in the boys who do not have drive, confidence, opportunities, or resources to drift into pits of despair, rage, and resentment.
