Where have all the anti-war and peace songs gone?

Think about it. The country is bogged down in a mively unpopular war that has cost over 4,000 american lives, there are mive protests, (though the media doesn't seem to acknowledge them), like the march on the pentagon in early 2006, an economy that's going down the drain, unemployment, global warming, and the current presidential election. All of this is going on, and yet musicians in the mainstream area of music don't seem to pay any heed to any of it. Do they not care, or are the music companies just keeping them silent? I know there's a Ton of underground and indie bands that are speaking out against these issues, but the current system refuses to acknowledge their presence in the music scene. What's your thoughts on this? Keep your answers respectful. Thanks, peace.
