Community-scale banks (aka credit unions) are a better idea for local-regional communities (aka cities and towns and agricultural regions) because their managers have to live with their clients.

None of us may be able to pick the queen of hearts, but some of us have caught on to the fact that it's three card monte. When it all falls down, should we console ourselves with "well at least the banks weren't small and local and vulnerable to economic shocks"?
