How is that statement rhetoric or hyperbole (which are both defined by their use of exaggeration)? Is there anyone (Republican or Democrat) who believes we'll be able to pay off the nation's debt in this generation?
Of what generation are you speaking? There are large populations of at least five generations still living: the "Greatest", the "Boomers", "Gen X", the "Millennials", and then whatever they decide to call the kids born after 2003.
