The human brain is wired to fear scarcity and solve problems. When technology and capitalism fulfill most basic needs, this problem-solving instinct doesn't disappear. It latches onto more abstract, often social or political, issues, fueling neurosis and creating a population that externalizes its anxieties onto the world.

Existential angst is a luxury problem. A century ago, life's purpose was clear: survive. The comfort and freedom of modern life have removed physical struggles but introduced complex psychological ones, like finding meaning and identity, which are a hidden cost of progress.

Many of today's health and behavioral problems are caused by the "mismatch hypothesis." Our brains evolved for a world of scarcity and danger, which is maladaptive in our current environment of abundance and relative safety, leading to issues like obesity and anxiety.

Constant exposure to global crises like political polarization causes a 'collective amygdala hijack,' putting society into a chronic defensive state that impairs higher-order thinking and empathy. In this state, we lose nuance, become more prone to tribalism, and are easier to control.

Unprecedented global prosperity creates a vacuum of real adversity, leading people to invent anxieties and fixate on trivial problems. Lacking the perspective from genuine struggle, many complain about first-world issues while ignoring their immense privilege, leading to a state where things are 'so good, it's bad.'

The human brain is not optimized for changing its mind based on new data, but for winning arguments. This evolutionary trait traps people in their existing frames of reference, preventing them from assessing reality objectively and finding effective solutions.

This concept, 'prevalence-induced concept change,' shows that as significant problems decrease, our brains don't experience fewer issues. Instead, we expand our definition of a 'problem' to include minor inconveniences, making neutral situations seem threatening. This explains why comfort can paradoxically increase perceived hardship.

Our constant access to luxury goods, leisure time, and reinforcing substances is a new type of stress. Our brains, which evolved for a world of scarcity, are not equipped to handle this overabundance, leading to compulsive overconsumption and addiction.

The popular assumption that the brain is optimized solely for survival and reproduction is an overly simplistic narrative. In the modern world, the brain's functions are far more complex, and clinging to this outdated model can limit our understanding of its capabilities and our own behavior.
