I don't understand the first sentence; my understanding is that debt is having less than zero dollars, or having more money to pay off through loans or whatever than one's income can provide.

As to why U.S. citizens don't fully understand this is because of a combination of self-serving attitudes, short-sightedness, and superficial compassion. Everyone wants America to be prosperous, but they don't want to do anything to obtain such state.
