Havana residents are demonstrating remarkable resilience and solidarity amidst a severe economic crisis, exacerbated by Donald Trump's aggressive oil embargo. Despite disparities in living standards, the population has developed a strong "system D" or resourcefulness to survive daily. This is evident in the Old Havana, the capital's historic center, where even in normally tourist-heavy spots like the Vitrola restaurant, locals and the few remaining foreigners find ways to support each other, such as musicians accepting pesos and an elderly woman attempting to sell her smartphone for 8,000 pesos (approximately 14 euros) to afford food for her family. This ingenuity highlights the pervasive need for immediate income to sustain basic necessities.
