>it hasn't been studied much This isn't true. There's quite a lot of literature on it; even my basic macro textbook in university noted a correlation between government debt above a certain level and reduced GDP growth. https://www.mercatus.org/publications/government-spending/debt-and-growth-decade-studies https://www.mercatus.org/publications/government-spending/de... describes it: "A large majority of studies on the debt-growth relationship find a threshold somewhere between 75 and 100 percent of GDP. More importantly, every study except two finds a negative relationship between high levels of government debt and economic growth. This is true even for studies that find no common threshold. The empirical evidence overwhelmingly supports the view that a large amount of government debt has a negative impact on economic growth potential, and in many cases that impact gets more pronounced as debt increases."
