Money, get back
I'm all right Jack keep your hands off of my stack
Money, it's a hit
Don't give me that do goody good bullshit
I'm in the high-fidelity first class traveling set
And I think I need a Lear jet
Money, it's a crime
Share it fairly but don't take a slice of my pie
Money, so they say
Is the root of all evil today
But if you ask for a raise
It's no surprise that they're giving none away
The second and third verses paint a picture of the sort of person who craves riches. They're incredibly selfish, wanting to protect their own stacks of money instead of wasting them on "do goody good bullshit" charitable causes. Roger Waters himself frequently contributes to international charities.
They are in favour of sharing wealth through tax, but only if it doesn't hit them too harshly. Shortly before Money was written, The Rolling Stones swanned away to the south of France to avoid hefty tax. More recently, U2 have been criticised and accused of 'unethical' tax exile, made all the more pertinent by the socially conscious appearance of frontman Bono.
Money starts as an ambiguous piece of lyricism that simply puts the rewards of riches on a pedestal, but quickly turns the knife and is deeply anti-materialistic.
