Guido, I'm not exactly sure Favre did it entirely for the money. Sure, he embezzled hundreds of millions of dollars meant for low-income welfare Mississippi recipients for a volleyball court for his daughters, but IMHO, Favre's reasoning may have been to see if he could get away with it, a risk-prone adventurer who wants to stay viable in the public limelight.
Plus, I think Favre decided to engage in these schemes because he believes he's bullet-proof, a very popular sports celebrity from a state where he enjoys a lot of political and legal protection and the local, state-level politico smucks who were involved in these embezzlement schemes are expendable and more likely punished, but he won't be and so far, Favre's name hasn't been charged with anything in these scandals.
