Alternative 1: Slavery or Servitude: For the Unprepared
A long and detailed discourse on a possible / likely / inevitable societal collapse. This collapse will center on the USA, but impact the entire world: Scary!
Excerpts follow:
As the most heavily armed society in the developed world, the U.S. can easily go the way of well-armed criminal gangs controlling urban zones or well-armed militia sprouting up to take out the criminals. There is historical precedents for either scenario. A third scenario (common in the 3rd World) is for wealthy enclaves to hire private forces to protect the enclave.
While I can't predict which will play out in various circumstances, we should be aware that the U.S. has millions of military veterans and millions of weapons. The USSR had the vets but not the weapons in private hands. People will eventually choose to support an alternative to anarchy or criminal/mob rule, unless the criminal gang is the only alternative to something worse (i.e. the Sadr City scenario). Or people will pay extra to maintain a community police force and let go of the other city services, performing them communally via volunteer labor.
My point is simply that a heavily armed culture with tens of millions of firearm-trained vets is not going to follow the route of a society without those two elements.
