Poetry of Social Awareness

One of the things I love so much about good songs and poems is that they say important things in a powerful, creative way, and rarely come off as a) boring or b) preachy as the same thing said in plain language. I've already posted the lyrics on here for "Waiting on the World to Change" by John Mayer, which I think speaks to the apathy of a lot "young" people these days and why they feel there's no point in trying to make things better.
I write some of my own poetry and music, but I've never had a good knack for writing good "social/political commentary" songs, so when I find one I love, I like to share it. Here's a song that says a lot of things, speaking generally about hypocrisy and obsession with money, weapons, and power. Like I said, expanding it all out in plain language will likely be a) boring, and b) preachy, so enjoy the song instead. It's by Jack Johnson. A lot of his other stuff is great too, discusses nature, the importance of focussing on non-material aspects of our life, etc, but this song, Symbol in my Driveway, is the one that packs the most punch to me...
Here's a YouTube link to it... Never mind the "eSocialist" picture; I couldn't find his original vid.
