The term “Insoluble Insolvency” was created to address a fundamental fact regarding the federal debt; under accepted operating norms it is a foregone fact that the US government is going to become insolvent. Insoluble Insolvency means there is no politically, economically, and institutionally feasible path back to long-term fiscal solvency using conventional measures. To this end it aslo means real fiscal incapacity, not the mechanical exhaustion of dollars.
In lieu of spending government resources on attempting to develop a solution to an issue with a non-existence solution, the highest priority should be to build protective walls around fundamental programs such as Social Security and Medicare as explained in this link.
