The Federal Reserve recently reported that about half of Americans have virtually no wealth at all, with four in 10 unable to afford a $400 emergency expense. That means that if their car breaks down or their child gets sick, they have to charge those expenses to a credit card. And when they do that, they get ripped off - big time. Despite the fact that banks can borrow money from the Fed at less than 2.5%, the median credit card interest rate ... is now over 21%. Last year, Wall Street banks made $113 billion in credit card interest alone, up by nearly 50% in just five years. In other words, while working class Americans pay outrageously high interest rates, Wall Street banks get rich. And if you live in a low-income community without a bank or cannot get a credit card, what do you do when you need to borrow money? You may have to turn to a predatory payday lender where the average interest rate on an annual basis is a jaw-dropping 391%. When banks and payday lenders charge these unconscionably high interest rates, they are not engaged in the business of making credit available. They are involved in extortion. We need a national usury law that caps interest rates ... at 15%. And that's exactly what the legislation I introduced with Representative Alexandria Ocasio-Cortez would do. Under our Loan Shark Prevention Act, we would make sure that no bank or store in America could charge an interest rate higher than 15%. 88% of Americans support a cap on credit card interest rates.
