While a fixed pension return assumption is foolish, we shouldn't think that the money the nation needs to address these problems isn't available.   If we had the will we would be looking at the root causes of our extreme inequality in wealth.     Do we really understand the total glutony spawned by unlimited wealth?   And we admire this as 'success'?     

As a Christian, I know the bible has much to say about wealth, most of which 'liberals' would agree with, ( but would deny if put in a religious contex).     We have diminshed positive spiritual values by confusing them with church doctrine.     Its a pity that the universal doctrine of the  human Jesus, has become so fragmented by relgious arrogance.
