Or you could take Trump’s approach and get the economy running on all cylinders so that your tax revenues are higher and you can afford to keep your promises.
Even that’s not a viable solution at this point. Go ahead and do the math and see how much increase in GDP and tax revenue we would need to avoid default in the next 20 years. It’s impossible unless we have something akin to another industrial revolution.
But... if the economy picks up, it could delay the date a little bit, and it could reduce the need for more radical solutions a little bit, but we are still going to need radical solutions.
