Even though the video has their facts right, it should be noted that he his exaggerating greatly: yes, the money is created this way. But don't forget there are -many- laws created to counter this. I won't ever say this is enough, and that it is a fair system, but the effect the video describes is smaller than it might seem from the video.
People on earth are all, knowingly or not, "agreeing" with this system by living in the community. If you don't want it, no matter how stupid it sounds, you have to move to somewhere with no government that uses no IOUs or taxes.
Before the flames: I'm not saying I agree on the current monetary system, I'm just making sure people don't interpret it wrongly.
You're right, there are many laws that govern the creation of currency in the US, but I think if you have zero background in finance, this video is awesome in explaining the big picture on how it's created, you know?
