Washington (CNN) -- Being president pays; $400,000 a year, in fact. That salary has increased over time. President Harry Truman left office in 1949 making $100,000. When Richard Nixon entered the White House in 1969 the salary went up to $200,000. It remained there for 30 years, until Congress doubled the presidential salary effective in 2001, when President George W. Bush took office. Aside from the pay, there's the free transportation in the presidential limousine, Marine One and Air Force One. And don't forget the free housing in Washington's most famous mansion, complete with a killer view of the Washington Monument, along with other perks (a personal chef, for one).
