They would need to raise interest rates above the inflation rate to get ahead of it. The 8.6% is understated. Do you think a hike to 10/15/20% is possible? No. If the interest rate were raised to 10%, the US couldn't service its debt (by taking out new debt). So it would mean default, and the start of the "Greater Than the Great Depression". Of course that wouldn't be allowed to happen, so they would start minting those trillion dollar coins... and that would mark the beginning of the "Greater than the Greater than the Great Depression".
