Clients, suppliers, and partners receive hidden rebates and subsidies that much increase the - unreported - real cost of production.

BBVA's payments to ETA may have been a typical payment of protection fees. Both terrorists and organized crime put slush funds to bad use. They get paid from such funds - and maintain their own. Ransom payments to kidnappers often flow through these channels.

But slush funds are overwhelmingly used to bribe corrupt politicians. The fight against corruption has been titled against the recipients of illicit corporate largesse. But to succeed, well-meaning international bodies, such as the OECD's FATF, must attack with equal zeal those who bribe. Every corrupt transaction is between a venal politician and an avaricious businessman. Pursuing the one while ignoring the other is self-defeating.

Note - The Psychology of Corruption Most politicians bend the laws of the land and steal money or solicit bribes because they need the funds to support networks of patronage. Others do it in order to reward their nearest and dearest or to maintain a lavish lifestyle when their political lives are over.

But these mundane reasons fail to explain why some officeholders go on a rampage and binge on endless quantities of lucre. All rationales crumble in the face of a Mobutu Sese Seko or a Saddam Hussein or a Ferdinand Marcos who absconded with billions of US dollars from the coffers of Zaire, Iraq, and the Philippines, respectively.

These inconceivable dollops of hard cash and valuables often remain stashed and untouched, moldering in bank accounts and safes in Western banks. They serve no purpose, either political or economic. But they do fulfill a psychological need. These hoards are not the megalomaniacal equivalents of savings accounts. Rather they are of the nature of compulsive collections.

Erstwhile president of Sierra Leone, Momoh, amassed hundreds of video players and other consumer goods in vast rooms in his mansion. As electricity supply was intermittent at best, his was a curious choice. He used to sit among these relics of his cupidity, fondling and counting them insatiably.

While Momoh relished things with shiny buttons, people like Sese Seko, Hussein, and Marcos drooled over money.

The ever-heightening mountains of greenbacks in their vaults soothed them, filled them with confidence, regulated their sense of self-worth, and served as a love substitute. The balances in their bulging bank accounts were of no practical import or intent. They merely catered to their psychopathology.

These politicos were not only crooks but also kleptomaniacs. They could no more stop thieving than Hitler could stop murdering. Venality was an integral part of their psychological makeup.
