Why does the Consumer Financial Protection Bureau matter to investors?
The Consumer Financial Protection Bureau may not seem like an agency that should matter too much to investors, but believe it or not, it protects you, too. Not only does it ensure that financial institutions like your brokerage are on the up-and-up, but it can also collect complaints that may result in changes to how financial institutions collect fees or rules around how those fees are paid.
This allows you to go in with more trust as a customer and to feel a little better about any investments you make in financial institutions, since you know someone who has real power to change behavior is policing them. Of course, if you know going in that a financial institution has unethical practices, it's better to simply not invest in them. But sometimes, you don't know these things until it's much too late.
