Th[e] populist argument goes like this: Corporations have made it perfectly clear over the past 20 years that they have no social responsibility, and that their sole duty is to maximize shareholder value. Thus, you end up with banks that charge an average of $28.23 for a bounced check, and charge $4 to withdraw $50 from an ATM, and bamboozle consumers into getting unaffordable mortgages. That being the case, what’s wrong with consumers treating banks the same way?
