That's a great visual aid to bring the problem home. My only quibble is on that last graph. That's not the US National Debt, or even the Total US Debt (the debt owned by federal, state, and municipal governments, US corporations and private citizens) which stands at just north of $50 Trillion. Instead, that $114.5 trillion is what's called the US's unfunded liabilities. These are not funds that are owed to anyone, they are projected funds that will be expended in the coming decades that don't have a revenue offset. It's like a vendor committing to his suppliers to buy 50% more inventory every month forever, but his sales trends aren't increasing. He may not be currently in debt, but unless he starts selling more or charging more, he will be soon! Except this isn't a vendor, this is the entire nation, government and private sector included (though mostly government as private sector doesn't generally make these types of commitments).
So the statement "114.5 trillion dollars. This is the US debt now." is a bit misleading, but definitely a figure to pay attention to. It's a great graphic though!
