As the article point out these 58 Trillion debt is hold mostly by bankers. So how did this bankers earn this much of money to loan out? that's the magic of Fractional reserve .
Crypto currencies directly challenge this model . I have seen many MSM talking heads ask the question "what is bitcoin is backed by? " . Suddenly these pundits want to know what it's backed by isnt that funny?.
Not a single MSM pundit have an issue with Fiat money which is backed by nothing. They will say "it's the faith in government blah, blah" but these government central banks(US Federal Reserve) are owned by private banks and the government is in there pocket.
