Why isn't anyone writing great protest songs?
Write something, then define what it means. As opposed to, think about what it should mean and then write it.
James McMurtry's heart is in the right place, just not sure this song gets there.
BTW: McMurtry's one of my favorites in this realm, on the heels of Steve Earle. Bob Dylan, in recent years, is one of my biggest disappointments, on the heels on me.
