Creedence Clearwater Revival/WMG

The lyrics of "Fortunate Son" pertain to multiple wars that America has been involved in, not just Vietnam.
Let's break it down: ""Some folks are born made to wave the flag" - all Ooh, they're red, white and blue - all "And when the band plays 'Hail to the chief'" - since the Civil War "Ooh, they'll point the cannon at you, Lord" - all, mainly up to the Civil War

"It ain't me, it ain't me I ain't no senator's/millionaire's/military son, son It ain't me, it ain't me I ain't no fortunate one, no"

"Some folks are born silver spoon in hand" - all "Lord, don't they help themselves, oh" - all "But when the taxman comes to the door" - all, particularly the American Revolution "Lord, the house looks like a rummage sale, yes" - all

"Some folks inherit star spangled eyes" - all since the War of 1812 "Ooh, they send you down to war, Lord" - all "And when you ask them, 'How much should we give?'" - all "Ooh, they'll only answer 'More! more! more!'" - all"
