In this video, Motley Fool financials analyst David Hanson talks about the recent revival of the political discourse around the idea that several of the huge banks currently still considered "too big to fail" need to be made smaller. In so doing, they won't be forced to rely on government support again if another crisis occurs. David tells us the advantages that some of the enormous banks such as Bank of America (BAC 0.59%) and Citigroup (C -0.61%) have over smaller banks due to their size, and gives us a look at what is rekindling this debate today.
