Well, the numbers are bad, but not altogether hopeless. The score on the Gallup Confidence in Banks poll in
the NYTimes puts banks at 22, In 1979 they stood at 60.
I expect that bankers themselves will always provide enough support for themselves to keep it at about 10, so there are still one or two consumers out there with some confidence in the banks.
Spotting them will be hard, certainly if they aren't your customers.
