Those and other reasons make absolute sense, but I would imagine somebody to offer basic banking to the unbanked with a reasonable fee structure etc and just take the market. Germany's banking system is terribly customer hostile, but we've got that covered. The US is the motherland of disrupting old industries, why is it that it's not sorted out yet?

I get why some old self-important bank does not want to deal with the poor and makes faces if you suggest it, but somebody has to yell pecunia non olet and jump int.
