Three days after the world learned that $50 billion may have disappeared in Bernie Madoff's Ponzi scheme, The Times led its front page of Dec. 14 with the revelation of another $50 billion rip-off. This time the vanished loot belonged to American taxpayers. That was our collective contribution to the $117 billion spent (as of mid-2008) on Iraq reconstruction - a sinkhole of corruption, cronyism, incompetence and outright theft that epitomized Bush management at home and abroad. The source for this news was a near-final draft of an as-yet-unpublished 513-page federal history of this nation-building fiasco. The document was assembled by the Office of the Special Inspector General for Iraq Reconstruction - led by a Bush appointee, no less. It pinpoints, among other transgressions, a governmental Ponzi scheme concocted to bamboozle Americans into believing they were accruing steady dividends on their investment in a new" Iraq. The $50 billion ... pales next to other sums that remain unaccounted for in the Bush era, from the $345 billion in lost tax revenue due to unpoliced offshore corporate tax havens to the far-from-transparent disposition of some $350 billion in Wall Street bailout money. In the old Pat Moynihan phrase, the Bush years have "defined deviancy down" in terms of how low a standard of ethical behavior we now tolerate as the norm from public officials.
