RE SS: Social security has already crossed the point where SS expenses exceed SS tax revenue [1]. Interest on bonds purchased with SS tax revenue are paid out of general tax revenue. I see two issues with what you said. First, what matters is the expected return and whether it's prositive. I can sell you an "investment" that pays dividends and raises revenues, but that doesn't mean it is net positive economically. I can spend $100 to raise revenue by $0.01 for 10 years. Is that an investment simply because some nonzero level of return? Second, waving away debt as internal ignores the fact that interest recipients and payers are different. A family with a big credit card bill is also domestic debt and circulation. That is little consolation for the family spending an increasing portion of their budget servicing the debt, nor is it consolation that the money is being circulated by their banker paying their housekeeper. The internal "who" matters, especially when some people can run up the credit and check out before the bill comes do. https://www.ssa.gov/oact/STATS/table4a3.html https://www.ssa.gov/oact/STATS/table4a3.html
