And Poland's plain, and England's grassy lea
And torn from Black Africa's strand I came
To build a "homeland of the free."
The free?
Who said the free? Not me?
Surely not me? The millions on relief today?
The millions shot down when we strike?
The millions who have nothing for our pay?
For all the dreams we've dreamed
And all the songs we've sung
And all the hopes we've held
And all the flags we've hung
The millions who have nothing for our pay--
Except the dream that's almost dead today
O, let America be America again--
The land that never has been yet--
When this poem originally came out in the late 1930’s, the Great Depression had been going on for about eight years already. People were out of work, the U.S. dollar was not worth as much as before, and one of the worst droughts ever hit the plains; causing the “dust bowls”, which destroyed farming and crops. This great depression didn’t end until America joined the war in 1941, which stimulated their economy.
