This doesnt nees to be done. They just cant be allowedd yo do what they did prior to 2008 melthdown. Aka detugulation of banks is what lead to it. Just regulate or oversee so that the oversight can let us and oyher government agency know when they are building a bursting bubble scenario. If they cant allow banks to be regulated in the manner in which Bush jr got rid of then yes they should be broken up. But until yhen this is the answrr that keeps the top 1% keeping their mega banks while not putting the world economy at risk.
