In the book "Outliers: The Story of Success" by Malcolm Gladwell, the development of Rosetan culture is highlighted as a community effort. Residents engaged in gardening by cultivating potatoes, melons, and various fruit trees, which transformed the long backyards into productive spaces. This initiative not only brought life to the town but also fostered a sense of community and sustainability, as people began raising pigs and growing grapes for local wine production.

As the community thrived, infrastructure followed suit. New schools, parks, a convent, and a cemetery were established, reflecting the growing population's needs. Garibaldi Avenue became a bustling hub with small shops, bakeries, restaurants, and bars catering to locals. Additionally, the town witnessed industrial growth with the establishment of over a dozen garment factories. This vibrant mix of cultures, including influences from Welsh, English, and German immigrants in neighboring areas, contributed to the unique fabric of Rosetans' society.
