Can inflation or default fix ongoing primary deficits?
Core argument: CBO long-term projections show steady primary deficits of 2% of GDP driving a slow explosion in the US debt-to-GDP ratio, a scenario the CBO itself labels "unsustainable.".
Figure 5.4 plots the Congressional Budget Office long-term projections for debt to GDP and deficits. The steady 2% of GDP primary deficits lead to a slow explosion of the debt to GDP ratio. These projections assume that nothing bad will happen again. Surely something bad will happen at some point in the next 30 years. The US will want to meet future crises with more borrowed or printed money. Yet, as forecasts, these projections are too pessimistic. This scenario will not happen. The CBO itself labels the scenario “unsustainable.” Debt to GDP cannot grow forever. The only question is how it will not happen. The good news is that fixing a 2% of GDP fiscal gap in a prosperous, growing country at peace is not that hard as an economic matter. As straightforward as a fiscal reform is as a matter of economics, it does seem to be beyond the capacity of the current US political system. Inflation or default will not cure the US or other advanced-country fiscal problems. The fiscal problem is prospective deficits; poor prospects for repayment, not so much current debt. If we wipe out all current debt, we still must finance endless primary deficits. And the day after a $36 trillion default or Weimar hyperinflation, who is going to lend a trillion or so new dollars to the US each year?
