A key element of Hudson's analysis is the distinction between productive and unproductive debt. He posits that productive debt, such as borrowing for investments that generate economic growth, can be beneficial. However, unproductive debt, especially financial speculation and real estate bubbles fueled by excessive borrowing, ultimately destabilizes economies. This unproductive debt, according to Hudson, leads to asset price inflation and burdens future generations with debt servicing costs, diverting resources from productive investments.

Hudson's critique extends to the international financial system, where he argues that debt is used as a tool for imposing economic and political dominance. He highlights the role of international financial institutions, such as the International Monetary Fund (IMF) and World Bank, in perpetuating debt cycles in developing countries, which often leads to economic hardship and political instability.

Furthermore, Hudson emphasizes the historical context of debt, tracing its influence throughout history. He points to ancient societies where debt jubilees were practiced as a way to prevent excessive debt accumulation and social unrest. He argues that modern economies could learn from these historical precedents to mitigate the destabilizing effects of debt.

Central to Hudson's economic perspective is the concept of rentier capitalism. He defines rentiers as individuals or entities who derive income from owning assets, rather than producing goods or services. According to Hudson, rentier capitalism leads to increasing inequality and economic stagnation as wealth is concentrated in the hands of a few, while the majority struggle with debt and declining living standards.

Hudson's work has gained significant attention in recent years, particularly in light of the global financial crisis of 2008 and the subsequent rise in public debt levels. His analysis provides a framework for understanding the complex dynamics of debt and its impact on economic stability and social justice. He advocates for policies that address the structural imbalances created by excessive debt, including debt forgiveness and stricter regulations on financial institutions.

In essence, Michael Hudson’s economic theories challenge conventional narratives about debt and offer a critical lens through which to analyze the modern economic landscape. His work emphasizes the importance of understanding the historical context of debt, distinguishing between productive and unproductive forms of debt, and addressing the challenges posed by rentier capitalism. By exploring these complex issues, Hudson encourages a more nuanced and informed discussion about the role of debt in shaping economic and social outcomes. His perspective provides valuable insights for policymakers, economists, and anyone seeking to understand the dynamics of the modern financial world.
