In 2009, in an effort to maximize tax revenue, the federal government offered amnesty to people who illegally hid money from taxation in offshore accounts if they agreed to pay back what they owed plus interest and penalties. 15,000 Americans came forward to accept the offer, ponying up cash to avoid felony prosecution.
Mitt Romney is somewhere around the 3,140th richest American. He made his money in financially complex and opaque ways. He has admitted to having bank accounts in the Cayman Islands, Bermuda and Switzerland. His massive IRA worth tens of millions despite relatively-tiny contribution limits indicates his ability and willingness to manipulate the tax code. He has fought tooth and nail to avoid releasing any taxes from before 2010.
In light of these facts, one must ask oneself "is Mitt Romney one of the 15,000 most likely people to have participated in the amnesty program?" Isn't the answer undoubtedly "Yes!"?
