Data suggests that growing up without a biological father is a stronger predictor of a young man ending up in jail by age 30 than either his race or his family's income level. This highlights a profound social crisis rooted in family structure, distinct from purely economic or racial factors.

Risk assessment tools used in courts are often trained on old data and fail to account for societal shifts in crime and policing, creating "cohort bias." This leads to massive overpredictions of an individual's likelihood to commit a crime, resulting in harsher, unjust sentences.

Sociological research shows the era a person is born into—the "birth lottery of history"—is a more significant predictor of criminality than individual factors like psychology or poverty. Just a few years' difference can double the arrest rate for people from otherwise identical backgrounds.

Society must abandon chronological age as a proxy for ability. People in their 30s can be non-functional, while centenarians can be perfectly functional. The focus should shift to an individual's actual health and capacity, unlocking the potential of older individuals instead of devaluing them based on their birth date.

Contrary to the ageist view that an older population drains resources, healthy older individuals represent a massive, untapped asset. Their accumulated wisdom, experience, and wealth are a form of "gold" that society must learn to mine by creating opportunities rather than pushing them aside.

Data from the world's longest-lived populations shows the distribution of death is compressing, not shifting to older ages. More people are reaching old age, but the curve is getting tighter, proving a biological wall for average life expectancy around 87 years. This reinforces the need to focus on healthspan.

CZ’s first-hand account reveals that the US prison system segregates inmates by ethnicity (e.g., Chinese, white, black, Hispanic) into groups or "cars". This practice is encouraged by guards as a method to reduce friction and manage conflict through group representatives.

The American housing market is increasingly inaccessible to younger generations. The median age of a homebuyer has hit a record high of 59, the same age one can access retirement funds. Even the median first-time buyer is now 40, indicating a systemic affordability crisis.

The idea of a stable "criminal character" is a trap. Societal conditions can completely override individual traits like self-control. A person with high self-control in a high-crime era was just as likely to be arrested as a person with low self-control in a later, lower-crime era.
