Pardon the double post, but I had to reply to the second post first, and then I lost my orginal train of thought on the first. Here it is.
Can the US abandon the colonial phase similar to European countries a century ago it's currently going through? Abandon it's desires to dominate and conquer smaller countries and demonise peaceful regimes with different value systems? Cut it's military spending by 400%?
Granted some of the U.S policy decisions, like Iraq, were poor choices. But the general policy of imperialism had worked admirably for the U.S. I dont feel as though a major policy shift is needed. I do agree that the U.S military is too expensive. The solution to cut spending however is not found there but in the social programs and other socialist aspects of domestic policy.
Overthrow it's aristocracy of super rich family dynasties that living lifestyles akin to 18th century French aristocrats who are the only people in the country allowed to hold high office and become a democracy where anyone may become leader of their country based on ability not accident of birth?
There is no law that prohibits anyone, other than minors, from occupying political office. Realistically most elected officials are members of the upper or middle class. But that is a natural result of democracy. Even though some people are poor by no fault of their own, many are simply unable to make a living or balance their budget. Either way the perception is that poor people are unfit. People want the most competant, successful individuals leading them, and thus few of the poor are ever elected. (Though there are certainly notable acceptions, Lincoln for instance).
Decentralise as a nation, returned all the power erroded away from once independant states giving local people real power over their lives again?
With this I would agree. The U.S Federal government has to much power and is quickly becoming a totalitarian state, though not nearly so much as most of the nations of Europe.
Improve working conditions increasing low wages, reducing working hours, tripling holiday allowances and creating genuine workers rights legislation? Radically overhaul the tertiary social security system providing free medical treatment of equal quality for all, not just politicians? Create a court of human rights, abolish torture and state sanctioned murder?
That is socialism and internationalism, both of which are, in my opinion, very very poor policy. If you intend the U.S to go in that direction, perhaps you should give some reason..
