"Frank 6 % guaranteed, year in and year out, isn't a bad return you know. Don't sniff at it many of our larger coporations would be happy to earn this return on their activities..."
You do realize that a 6% dividend share is in fact 6% ROE for the member banks since the shares are not tradeable, right? In that case, you might want to look at this graph: http://images.flatworldknowledge.com/wright/wright-fig10_005.jpg?sessionGUID=4c7c7834-27c6-30b8-7cc8-20ce134a5dbc&webSyncID=7168c318-390a-61a8-322

As you can see, such a ROE was not surpassed by industrial average only seldom in the 1935-2008 timespan. In 2010, it was back to 7% again. A long-term 6% ROE is nothing any bank would take pride in. Even with tightened regulatory framework, the banks will outperform 6% ROE with ease even though it won't be business-as-usual 10%+.
