Look at one of the dakotas for the best example of a state bank. There are only two states operating them. It's huge that every state have them. Get rid of the 14th amendment and get states back to setting tariffs on imported goods same as national govs. Thatbwill be their only operating capital. No more national companies taking money out of states leaving them poorer. No more interest on loans. No more taxes of any kind. South Dakota is doing very well with it. Usery is misery.
