No, because government officials are paid off much less often because it's harder.

Outright bribery in the US is rare, difficult, and if caught, will land you in federal prison for a long time. Remember Blagojevich?

Government officials are under much more scrutiny than a private sector executive. There are independent investigators general that have broad latitude to look for malfeasance. The FOIA exists to bring government records to light; there is no equivalent in the private sector. Heck, we spent ~$80mm investigating Clinton over the Lewinsky affair.

The government isn't perfect, but it's a damn sight more transparent and directly accountable to the public than private companies are.
