Is the gross amount of US debt dangerous for the small investor?
Not a lot, directly. Your biggest direct risk is that you could buy the debt, and buy it at too high a price (i.e. too low an interest rate) and not make as much money as you ought (and maybe not enough to cover inflation, especially if you buy long-term bonds at low interest rates.) The indirect risks are mostly that the debt could weigh on economic growth: There is also a question of monetary policy, inflation, and interest rates set by the Federal Reserve. Theoretically the government could be tempted to keep interest rates low (to save money) and buy its own bonds ("printing money"), which could cause inflation. Theoretically, they shouldn't, as price stability is one of the Fed's primary mandates. But if they did, inflation makes everything less predictable and is generally obnoxious, which makes everything more risky and drags on the economy. Also, if the nominal value of an asset rises due to inflation, you will likely need to pay taxes on that at some point if you sell it, even though its real value is the same.
