The US National Debt is at about 31 trillion US$. With the recent increases in interest rates related to the "fight against inflation", the average interest the US debt pays is about 4.5%. This makes the yearly interest payments for the debt to be around 1.4 trillion US$. This represents close to 1/3 of the US federal income.
All this means is that the amount of debt is enormous and the only way to get out of it is to increase the GDP (therefore increasing federal income), and reducing the interest rates. Very difficult to achieve in an inflationary environment. An alternative is to use inflation as a hidden tax, but this will go in detriment of the quality of life of the people
