The Consumer Financial Protection Bureau (CFPB) turned just three years old Monday, July 21st, but when you look at its massive and compelling body of work, you must wonder: Are watchdog years like plain old dog years? Is the CFPB now a full-sized, 21-year-old adult? The answer is no, not yet. The CFPB is still growing and developing and adding programs and projects. The CFPB is, however, at three years old, certainly a child prodigy. Despite overwhelming public support, however, powerful special interests continue to attack it. Yet, the idea of the CFPB needs no defense, only more defenders.
