I just heard about something called the petrodollar scam. Most people have probably heard about it already, but it's real news to me. The scam is the U.S. deal with OPEC to sell oil in dollars.
I guess several decades ago, we printed lots of American dollars and didn't know what to do when countries wanted to exchange dollars for gold, which apparently we didn't have.
What's shocking to me is that we are said to have literally gotten oil for free since it was all in dollars. But now that countries like Iran and Venezuela are selling oil in euros, they say that the scam is out. If we are forced to buy oil in euros in the future, our economy might go into depression.
