In this segment he singularly cites the actions of loan officers soliciting incorrect information comparing their actions to teachers falsifying test results.
First of all, loan officers are hardly "Wall Street" fat cats. They are low level employees who are paid an average of $50,000 [1] and do not work for "Wall Street" firms like investment banks.
Secondly, loan officers operate throughout the United States rather than actually on Wall Street or in Manhattan and, as a group, are subject to the jurisdiction of the federal government, 50 states, and 3,144 counties each with independent prosecutors (elected state's attorneys, district attorneys, etc.).
If none of the thousands of entities who could have brought cases have done so, either there is conspiracy vaster than any other or there are not credible cases to bring.
