Well I'm surprised nobody has mentioned my own personal favourite, which I used to sing a lot back in my 'bitter and twisted' days.
A song performed by Donovan called GOLDWATCH BLUES with this wonderfully evocative chorus,

Here's your gold watch and the shackles for your chains
And your piece of paper, to say you left here sane
And if you've a son who wants a good career
Just get him to sign on the dotted line and work for 20 years
