Trump had a moment this week when he acknowledged the U.S. cannot ever pay off the debt, and the country would move quickly toward insolvency if interest rates rose just a few percentage points. This has been a consistent topic on this site over the past few years, but it is unprecedented for a Presidential candidate to be so honest about the United States' pending bankruptcy and/or debt renegotiation.
Trump has quickly backtracked off the comments and later said America will "print the money" needed should interest rates rise. This calmed everyone back down, which is insane because the latter solution is far worse for the country over the long term. Please note Hillary's plan is also to borrow and print money, so this is not a targeted attack on Trump.
