Sorry I have to comment
The Banker position is similar to the General you have no actual power your only chance to gain it is to make people trust and believe in you to attain and make any progress. If the banker can't do it hell go to the judge they have power ^_^, though you have to make them believe you, but hey if you do get them fine better have some support through out the realm or they will not vote you into anything!
Also, if your realm/region starves... blame is on the banker but really it's that region lords fault
