Credit card interest rates are currently averaging 20-22% according to industry data, and APRs near or above 30% now exist and are increasingly common for store and retail cards. Whether those rates are "insane" is a value judgment—people reasonably disagree on what constitutes excessive. The post ties this to criticism of Wall Street, which is also a political judgment call. The broader picture is more complex: high rates reflect both lender risk pricing and market competition, not just 'greed,' and many consumers can still access 0% promotional rates depending on their credit profile.
