Public vs. Private Debt: The Interconnectedness and Impact on Economic Health

As someone concerned with the amount of public debt, it is important to acknowledge the significant role of private sector debt. While private debt is often considered 'good' debt, invested in assets that may appreciate in value or help grow a business, public sector debt remains a more pressing concern. This article aims to clarify the relationship between these two types of debt and their impact on economic health, using data to support my arguments.

The Link Between Public and Private Debt

There is a misconception that public and private debt are unrelated, exacerbated by ideological discussions such as those sparked by Kevyn. Contrary to this belief, there is a clear connection between the two. Whenever public debt falls below approximately 3% of GDP, modern economies have experienced recessions. However, when public debt consistently exceeds 3% of GDP for a sustained period, it can lead to economic depressions, as evidenced in history. For instance, the U.S. economy experienced significant private sector debt growth during the late 1990s and early 2000s, driven by both stock and real estate bubbles, which eventually led to a major recession in 2008.

Historical Perspectives and Data Analysis

Let's explore the data to provide a more concrete understanding. The government's net surplus periods from 1998 to 2001 resulted in increased private sector debt and lower savings. According to the reference chart, household consumer debt in trillions of dollars shows that in 2015, consumer borrowing in real terms was nearly identical to the 1990s levels. This indicates that while public surplus can lead to increased private debt, the correlation is not always straightforward.

The relationship between public surplus and private debt is also evident in savings. The chart below illustrates how a public surplus can lead to a private sector deficit, thereby reducing overall savings. This dynamic reflects the complex interplay between different economic sectors and the role of government debt in shaping private sector behavior.

Implications of High Public Debt

The argument that failing to repay debt is a Ponzi scheme is false. Historical data from World War II in the U.S. showcases that high public debt did not cripple the economy in subsequent decades. In fact, the 1950s and 1960s saw some of the best economic times in U.S. history, marked by high savings rates and low private debt due to significant government spending to support the war effort.

The chart below demonstrates the relationship between government debt and private sector assets. As government debt increases, private sector assets tend to increase, barring any foreign sector influences. This counterintuitive finding underscores the complex dynamics at play in economic systems.

Modern Challenges and Future Projections

Recently, a significant increase in government debt has been observed, leading to concerns about the future. One of the key issues is the extent to which government debt is used to extinguish private sector debt. For instance, a significant portion of the government debt reduction may eliminate private sector debt, effectively canceling out the debt and leaving no net financial impact.

Another critical point is the distribution of economic benefits. During the recent recession, a major portion of the wealth (non-home wealth) decline was not evenly distributed. Instead, the top 20% of the population captured most of the wealth, further concentrating resources at the top. This highlights the need for a more equitable distribution of economic benefits and the potential risks associated with rising private sector debt.

As governments around the world (such as the U.S., Japan, Australia, UK, and Canada) attempt to reduce debt and deficits, it is crucial to recognize that this approach may inadvertently fuel private sector debt. The data and historical examples provide a strong case for a more balanced approach to managing public and private sector finances.

Conclusion

The interplay between public and private debt is complex and multifaceted. Historical data and modern economic indicators suggest that while public debt can lead to increased private sector debt and reduced savings, the relationship is not always straightforward. As nations continue to grapple with high public debt, understanding these dynamics is crucial to avoid exacerbating economic challenges. Governments must balance their efforts to reduce debt with strategies to support sustainable economic growth and prevent the concentration of wealth in the hands of a few.
