Why are there many small banks and more banks in the U.S.?
In the US, paper checks are still the rule, and there is a large amount of the population that does not care to use online banking. As a result, those people need to go to the bank once a week or more often, to deposit checks they get from anywhere, to get cash, etc.; so all those little banks have traffic. This is slowly changing, and banks start to automatic the processes even in the brick-and-mortar location, but for now, they are around.
