It America is so great, then to whom is it in debt to? That's curious. Or are they in debt amongst themselves? Which would be the funniest thing ever.
They issue debt, in the form of T-bills, which others can buy. The two biggest are actually China and Japan. If you have mutual funds, you most likely have some in your portfolio as it's viewed as a very safe investment.
Will they ever pay them back? I very much doubt it.
