To understand how San Diego reached a state of abandonment, we must examine its early prosperity. The city relied heavily on three main pillars:

• An active commercial port on the Pacific Ocean.
• A massive military base and naval presence providing jobs and stability.
• A thriving tourism industry fueled by sun and sea.

This strong foundation created immense optimism, much like the meticulously organized hubs seen in ancient marvels such as Harappa and Mohenjo-Daro: The Mystery of the Organized Cities.

Despite its brilliance, San Diego’s economy harbored severe vulnerabilities. Overreliance on a handful of industries rendered the city susceptible to external economic shocks. When foundational pillars are tightly clustered, any major global trade shift can shatter the economy. Similar economic and structural shifts have dramatically altered settlements throughout history, echoing the mysteries found in How Nature Erases Borders: The Sistan Conflict and Lake Hamoun.

In late 1929, the Great Depression struck the world. For San Diego, this blow came like a relentless wave carrying away stability. The government drastically cut defense budgets to save costs, shrinking naval manufacturing and shipyard operations. Simultaneously, tourism completely collapsed as affluent visitors lost their financial means to travel, leaving luxury hotels empty with covered chairs and turned-off lights.

As conditions deteriorated, residents made difficult decisions. Families locked their doors and embarked on a quiet exodus, leaving behind a San Diego whose vibrant features were vanishing. Shop windows were covered in dust, and ‘For Sale’ or ‘Closed’ signs appeared on every corner. Hunger, despair, and isolation became the bitter reality for those who remained.
