Nrchy,
Are you mad at Rage Against the Machine because they work for a big record company? Or at Ani DiFranco because she started her own in protest? You can't have it both ways, my man!
In the end, I don't think you are listening very carefully to any of this music. Do you really think Simon and Garfunkel wrote protest music? Great stuff, and it speaks to a certain teen and twenty-something angst, but nothing's being protested.
The reason you think "protest music" is all done by millionaires (I'm not sure you should be putting DiFranco in the millionaire category, btw) seems to be that you are only listening to "big acts". Dig a little deeper and listen to the suggestions given above.
I love Pete Seeger (the Weavers were the first recorded music I remember hearing as a kid). As a straight-ahead folkie, though, he's by self-definition not a musical innovator. People like U2, Bruce Cockburn, Rage Against the Machine, and Public Enemy have pushed musical as well as political boundaries.
Let's hope people will continue to see fit to put whatever moves them into music.
