People feel lonely because they fill their finite capacity for social connection (Dunbar's number) with one-sided parasocial relationships from social media. These connections occupy mental "slots" for real friends, leading to a feeling of social emptiness in the real world.

For generations, increasing wealth allowed Western society to discard essential cultural norms like social trust and shared values. Now that economic growth is faltering, the catastrophic consequences of this "death of culture" are becoming fully visible.

While physically detrimental, alcohol's benefit in facilitating social interaction—a powerful mitigator of mortality risk—can outweigh its harms when consumed moderately in social settings, not alone or to excess.

For millennia, humans consumed weak, fermented beverages in communal settings, providing natural limits. The recent inventions of distillation (high-potency alcohol) and cultural shifts toward private, isolated consumption have removed these biological and social guardrails, making alcohol far more dangerous than it was historically.

Given high rates of social media addiction (24%) versus alcohol addiction (6%), the dangers of loneliness are arguably greater than those of moderate social drinking. Facilitating in-person bonding via alcohol could be a net positive for young people's well-being.

We spend more time alone due to structural factors and technology that enable avoiding interaction. This 'interiority' is a self-reinforcing cycle: as we interact less, our social skills can atrophy and social inertia sets in, making it progressively more difficult and energy-intensive to re-engage with others.

Ross Douthat points to a surprising social trend as a warning for a future of abundance. Despite unprecedented freedom, people are having less sex and forming fewer relationships. This suggests that addictive digital entertainment can overpower even fundamental human drives, a bleak indicator for a society with unlimited leisure.

Contrary to headlines, Gen Z's drinking habits are nuanced, not absent. Consumption is delayed by later workforce entry. In-the-workforce Gen Z drinks similarly to prior generations but practices 'zebra striping'—alternating alcoholic and non-alcoholic drinks for more conscious consumption.

Unaffordable housing is the root cause of many social problems. It statistically correlates with lower marriage and birth rates, increased alcohol abuse, and declining mental health, as it prevents young people from achieving a key milestone of adulthood.
