It is interesting that the U.S. Department of Justice did not pursue the fraudulent bankers on Wall Street not only during the Bush presidency, but also the following presidency, that of Barak Obama. Not coincidentally, Goldman Sachs was the single biggest campaign contributor to Obama’s 2008 candidacy for president. It would seem that Wall Street had both political parties in a net by the time of the financial crisis in September, 2008. A sector of the economy being able to control both major parties is bad for not only industrial policy (i.e., favoritism), but also democracy. In short, a government should have enough strength to constrain a business sector, rather than being subject to it. The latter condition implies continued vulnerability should greed again get ahead of itself on Wall Street. By nature, greed, if allowed to go on running on its own steam, accumulates more and more momentum.
