With the U.S. credit rating down, is there any way up?

Earlier this month, Fitch downgraded the U.S. credit rating from AAA to AA+. It was the first time the country’s rating dropped since 2011. What does downgrading the credit rating mean? How did it happen? And what does this all mean for us? Dr. Marco Airaudo is a professor of Economics at Drexel University's Lebow College of Business. He explains what it means for the U.S. credit rating to be down and how this affects us.
