That's awesome that WF is paying $3.7B. Unfortunately the victims will likely never see any of that. That money will just go into the treasury.
I would personally like to see the CPFB have the power to sue banks on behalf of customers to get financial redress. This money needs to get back to the people who suffered the most.
Hell, paying only $3.7B with a pinky promise you won't do it again would still be profitable if you made $5B on the scheme.
