Perspective is aided by comparisons. When you see the Grand Canyon on TV most of the perspective is lost. When you see the Grand Canyon in person or when you superimpose a scaled image of the local sports arena over a scaled image of the Grand Canyon, perspective is restored. This video does that for our national debt. Like the Grand Canyon, the enormity of the subject is not conveyed by numbers and descriptions. However, comparing the national debt to other countries' gross national product sets your perspective a lot straighter.
