Oddly enough, this law was designed for consumer protection. At only 2% of the balance, it would take decades to pay off a credit card by applying only the minimum payment. By merely doubling that payment to a 4% of the balance, it takes only a few years, saving time and thousands of dollars in interest charges. The bad news is if you already have a bad debt habit.
edit: And oh yeah, people will know this now. The Bankruptcy Abuse Prevention and Consumer Protection Act of 2005, which is taking effect and requires these increased minimum payments, also requires that every credit card bill include a warning show how long it will take to pay back the debt if only the minimum payment is made. Look for these next month.
