Poverty, schools, teachers, opportunity, etc.
I like Coleman Hughes analogy of a treadmill.
And anyone in any shitty situation that seeks to blame others and feel sorry for their self instead of setting goals and working harder will not succeed. The "systemic racism" stuff pushed by the left, even if true isn't at all helpful. This is where the influences such as parents, coaches, teachers and mentors is hugely important. Especially for young males.
