When your last job was "leader of the free world", life could be a lot worse. Unlike the common people who had to be vigilant to thieves and the odd house burglars, former US presidents are accorded Secret Service protection (George W. Bush becomes the first former president who does not receive life-time protection. A new bill was passed recently, limiting protection only up to 10 years after living office). Unlike the average Americans who may have to find a new smaller house (after their McMansion was foreclosured), Mr. Bush can raise donations from the public to build his presidential library (where as tradition is a fairly big complex and where tradition dictates, he gets to build a replica of the Oval Office). The federal government also pays him an estimated USD 200k per annum plus expenses to run his office and pay for his staff. Some presidents even get to keep their daily transport (Reagan, his Air Force One and Marine One , plus his motorcade; Clinton his Cadillac One).
It does not stop there. Unlike their normal compatriots though, when it comes to future employment, the group is spoilt for choice. No "work" (of the traditional definition is involved). Presidents easily are paid a minimum USD 50k for making speeches. Then there are also directorships or other board appointments in well known companies.
What is the point of all this, you may ask. Stick around, more will be revealed.
