The tyranny of scale creates terrible incentives in banking. Someone whose average balance hovers around $100/month might well cost the bank more money than they can earn off the balance, while someone with $10,000 is basically free.

Normally in services you charge more from the people who are more able to pay, because they'll be willing to spend more money for the same service. Yet in financial services and banking, the more money you have to spend on the services results in the lower fees and costs across the board.

I think if there's something that needs to be systematically altered to close wealth gaps, that's a fine place to start.
