You make a good point. Left unchanged we will lose simply by doing nothing. Of course that begs the question of who and what are we? Are we willing, at perhaps great sacrifice, to stand up and protect that which was protected and handed down to us or are we just going to ignore it and pretend. Maybe we really have become our own worst enemies.
