If small town 'murica is dying because no one is popping out 8 or more children, well, welcome to the modern world. Large families were required on family farms simply as a way of getting help, which is much reduced these days. And the children that are born into that life, see the bright city lights and the hustle and bustle of Des Moines and decide that is where they want to be.

Nope, small town America, as seen in The Music Man, is dead and gone forever. Nothing is going to halt its decline nor bring it back.
