Border Barrier Control/Patrol Elevated Highway on Mex Edge Sole Way of Halting Inflow of Revolutionary Internal Proletariat Next 30 Years for U.S.A.

http://en.wikipedia.org/wiki/Arnold_J._Toynbee The late (d. 1974) Arnold Toynbee described in his 'A Study of History' the way a civilization may allow an internal proletariat to grow exemplified with such as the mass relocation of Mexican workers illegally to the United States which eventually becomes a revolutionary class replacing the prior formerly creative majority that dwindles into becoming a repressive minority in power.

The wikepedia has a brief article on Toynee that has a paragraph describing the phenomenality of this one method of national self-destruction (it arises through greed and bad political leadership obviously). Toynbee believed that challenge-response was the fundamental nature of the social structure of civilization...

"When a civilization responds to challenges, it grows. When it fails to respond to a challenge, it enters its period of decline. Toynbee argued that "Civilizations die from suicide, not by murder."
For Toynbee, civilizations were not intangible or unalterable machines but a network of social relationships within the border and therefore subject to both wise and unwise decisions they made. If leaders of the civilization did not appease or shut down the internal proletariat or muster an effective miliatary or diplomatic defense against potential invading outside forces, it would fall.'

For the United States globalist forces politically overreaching advantage on borrowed money following the end of the post-world war two economic advantages have followed up the end of the bankrupt Soviet Union with an effort to de facto create a Toynbean version of a universal phase of a U.S. led civilization.

The Universal phase of a civilization is its last before decline. The process can be arrested however, and a standing waveform can be made to exist with a self-sustaing yet progressive independent economoy environmentally and socially interacting still with the global economic forces. Instead of leaving it in abstract forms what the government myust do is this...

1)Halt all illegal immigration into the U.S.A. peaceably, focus federal policy upon stimulating and supporting non-trade deficit producing policies through a cornucopia of national invention in macro-social energy and transport technology that allow citizens to become independent from centralized power and transport global controllers.
2)Immediately promote electric cars, home fuel ells for recharging, power lines in freeways for metered recharging, strong environmental zoning promoting zero net loss of biota.
