From some oldie song there is the line: the rich get richer and the poor get poorer..

Number of executives at Wall Street banks so far who have been tried on criminal charges related to the financial crisis: 2
Number acquitted: 2
Percentage tax rate that Goldman Sachs paid on its profits for year 2008: 0.6
