Annie Lowrey: “Consider how different our politics might be today if the economy had not collapsed in 2008 and not been mired in sluggish growth ever since. A ballpark estimate suggests that if the economy were to grow one percentage point more than expected in each year over the next 10, the deficit would shrink by more than $3 trillion. That would be more than enough to set the ratio of our debt to our annual economic output on a comforting downward trajectory. Moreover, it would happen without making cuts to a single program, like Medicare or food stamps, or without raising a single dollar of additional tax revenue. Even a much smaller boost to growth — say one-tenth of a percentage point per year, or even half that — would make Congress and the White House’s burden hundreds of billions of dollars lighter.”
