I'd recommend Seattle Jim Page.. he's prolific,
some Dan Bern, Michelle Shocked,
Murdoch has a good one in the works

I still like my own attempts esp.with 'Insurgent Sun','Anthem for Dissent',
'Big Muddee', 'Break Even', 'Change', 'Jabaliya', 'Mirage'...

as Mort Saul, and later Ochs, said, all you have to do is read a newspaper and make something up.. there's more to it than that, but I know what they're getting at... the money is lousy but it's good to get the frustrations out in a melodious/lyrical way... then maybe someone else won't feel as alone in their social perceptions... if that makes any sense at all... cats like Guthrie, Robeson, McCall, Seeger, early Dylan, Ochs, Dunn,and Murdoch did it for me.., made me think for myself, which is a dangerous thing for the Thought Police and their well dressed bosses !
