"Fortunate Son" was released as a single in late 1969. Songwriter John Fogerty intended the song as a protest against the Vietnam War. The song is critical of the fortunate sons of those in high places e.g. the political elite and/or the wealthy who are able to avoid the horrors of war for themselves or their relatives by benefiting from their privileged backgrounds.
Fogerty says that the song was indirectly inspired…
Some folks are born, made to wave the flag
Ooo, their red, white and blue
And when the band plays \"Hail to the Chief\"
Ooo, they point the cannon at you, Lord
