The article discusses the recurring issue of dollar shortages in Argentina, a phenomenon known as external constraint, which hinders economic growth. It highlights the structural imbalance between import needs and export capacity, worsened by debt payments and capital flight. The recent book 'Why are there always dollar shortages?' by Andrés Wainer and researchers from Flacso, including Pablo Manzanelli, Mariano Barrera, and Leandro Bona, is referenced for its analysis of this structural problem. The book examines macroeconomic issues and sectoral analyses, concluding that industrial investment reluctance and the role of state policy are key to addressing the external constraint. It also explores the relationship between salaries and external constraints, suggesting that other factors, such as capital flight and speculative behaviors, have a more significant impact on dollar shortages than salaries. The article argues for a transformative policy that promotes sustained economic development, investment, productivity, and job creation to improve workers' living conditions.
