John Fogerty hammered the American aristocracy back in 1969, for not having to send their sons to war – Vietnam. “Fortunate” is satiric, for the son not rich and connected enough to avoid the draft.
In 1999, Fogerty belted out this rocker in front of U.S. President Bill Clinton, but has said it was inspired by the grandson of President Dwight Eisenhower. This privileged boy married Julie Nixon, daughter to then current president, Richard Nixon. Camp David is the presidential retreat named after him.
Of course, there are many examples of American royalty (or at least, politicians) having served their country, including former presidential candidate John McCain, widely considered a war hero. Fortunate sons Bill Clinton and current President Barack Obama have not served, when all presidents before them have, going back to Herbert Hoover.
