BBI's post is excellent! There are historians who state that if you look at the fall of civilizations one major factor is the increasing divide among economic classes and the hollowing out of the middle. The inability of the average worker to provide a nuclear (not glowing) family environment is diagnostic of what we see. The failure leads to children without fathers associated rises in crime and drug abuse. Not to say that one must be in a Leaver to Beaver family but lack of family structure leads to societal disruption. It has been seen across the world.
Without solid jobs and families, civilizations fail. The elites, however, will prosper - until it all crashes. The angry will come over the walls of the gated community. Those who built retreats in missile silos and walled mansions with paid security, will see the security kill them and take their wives and daughters!
