The banks problem
If we do not stop the control of the money by the banker, it will have a problem. A lot of power are in the money, never forget it.
The bank's first goal should not to making money, but it should to give credit to population for buy thing for himself first, and at the end for liberate private economist (all the society benefit).
So if the banks are private, the first goal is (probably) making money because of the private goal. Of such kind publics banks is more appropriate because with the money they make, the gouvernement use it for services or for decrease taxes.
In an other order of idea, the fusion of banks in America to less than 100 in total is a good idea. However, the gouvernement (Senate, Common chamber and the President) as to write a law who can capture the bank. This law will be tought to be adopted because of the influence of the bankers, and they are corruption and influence in the higher floors of the Senat (gouvernor) and probably too in the Common chamber. However, it will be tough if news use propaganda, but in this war we can use propaganda and at the end of the day, like 99% of the people will be agree for the law. So, if it's really a democraty, the law will be pass. If not, it's a oligarchy.
