Please explain to me by your words, i need to understand this clearly. Thanks a lott.

1. What is the difference between Internal and External Debt, and which do we need to be more concerned about? Why is this the case?

2. Consider the quoted "But there are limits, and at some point, the United States will reach a tipping point...."

-What is the "tipping point" that the author is referring to, and why wouldn't the Fed be able to solve the problem that is identified in this statement?
