I will add credit unions are chartered banks...but unlike "banks" they are not owned by shareholders, they are non-profits made up of the members (account holders).

Ideally in 2008 all the "banks" should have gone bankrupt and the vacuum should have been filled with credit unions, instead lawmakers gave the banks $2T as a reward for ruining the US economy so they could float their own debts instead of declaring bankruptcy and enough so they could buy up their competitors to further consolidate the marketplace.
