For the Gangs of New York movie soundtrack, U2 sang in 2002 about a laundry list of issues concerning the USA.
While the lyrics are a little vague, the first verse is said to be partly concerned with the Irish Potato Famine/Great Famine (1840s-1850s) in which about a million Irish died and as much left, many for the USA. The song also gets into the American Dream – the ethos that rolling up one’s sleeves in a land of equal opportunity can bring success. Various ethnicities are listed as being the immigrants that made the country what it is. As if that doesn’t cover enough, 9/11 is thrown in for good measure at the end.
Perhaps the song is a first year university survey course on issues that U2 were thinking about in 2002… but inspiration to turn each part into a separate song did not materialize.
A search for “American Dream” at right will bring up several other songs on this topic.
