Where have all the fathers gone?

Recently at work I've been really struck by the lack of fathers in the lives of the youth of today. I work with teenage boys, providing a safe home environment for them. All of the boys I work with do not have their fathers apart of their lives. Some rarely see him some never see him. It is amazing to me that so many men have made the decision to not be apart of their child's life. How can it be that so many men are just dropping the ball? Failure to make the right choices, live with your decisions, and raise your son to be a honorable, honest, committed man. I don't understand how we got to this point. There once was a carpenter who risked severe ridicule and banishment to be the most important father in humanity, and now there are million of fathers incarcerated and incapable of being a role model. What happened?
