Without reading much of the topic, I'd say the reason for the lack of change is bullshit fed to us by our mighty tv sets sitting on our altar in the middle of the family room.
Example: I have been reading a lot into this global warming issue, and I no longer believe the earth is in serious threat because of humans, yet last night I was watching the mighty tv box, and somehow ended up in history channel, there was a show about "global warming". And let me tell you, I almost puked at how crappy info they fed the viewers, too much bullshit, humans are solely responsible for the earth's destruction due to warming says HC. History Channel, people watch this shows as if the people at HC wouldn't tell a lie.
There was no real information, nothing that proves anything, mostly it was a bunch of beautiful scenes like volcanoes erupting, divers on sea, ice caps, and a background voice saying something like "scientists have studied this phenomena, they have used data from volcanoes, co2 levels, etc... and they all agree, global warming is caused by humans."
Yeah thats pretty much what the show was, and the audience sees these things and believes every word.
I think comedy shows like jon stewart are more serious than these supposedly trustworthy channels.
If we're fed bullshit how can we even think about changing shit? how can we come up with a new way?
Its all tightly controlled by the few who set it up, only way I see change is through revolution, but that is demonized to no end by our tv sets.
Oh and by the way, not long ago I gave a quick study of the different isms and ways for societies to live and from the ones we know already, I came to the conclusion(IMO) that the best one so far is anarcho-capitalism:
http://en.wikipedia.org/wiki/Anarcho-capitalism (full wiki)
Anarcho-capitalism is an individualist anarchist[1] political philosophy that advocates the elimination of the state and the elevation of the sovereign individual in a free market. In an anarcho-capitalist society, law enforcement, courts, and all other security services are provided by voluntarily-funded competitors such as private defense agencies rather than through compulsory taxation, and money is privately produced in an open market. Because personal and economic activities are regulated by the natural laws of the market through private law rather than through politics, victimless crimes, and crimes against the state are rendered moot.
Anarcho-capitalists argue for a society based in voluntary trade of private property (including money, consumer goods, land, and capital goods) and services in order to maximize individual liberty and prosperity, but also recognize charity and communal arrangements as part of the same voluntary ethic.[2] Though anarcho-capitalists are known for asserting a right to private (individualized or joint non-public) property, some propose that non-state public/community property can also exist in an anarcho-capitalist society.[3] For them, what is important is that it is acquired and transferred without help or hindrance from the compulsory state. Anarcho-capitalist libertarians believe that the only just, and/or most economically-beneficial, way to acquire property is through voluntary trade, gift, or labor-based original appropriation, rather than through aggression or fraud.[4]
Anarcho-capitalists see free-market capitalism as the basis for a free and prosperous society. Murray Rothbard said that the difference between free-market capitalism and "state capitalism" is the difference between "peaceful, voluntary exchange" and a collusive partnership between business and government that uses coercion to subvert the free market.[5] "Capitalism," as anarcho-capitalists employ the term, is not to be confused with state monopoly capitalism, crony capitalism, corporatism, or contemporary mixed economies, wherein natural market incentives and disincentives are skewed by state intervention.[6] So they reject the state, based on the belief that states are aggressive entities which steal property (through taxation and expropriation), initiate aggression, are a compulsory monopoly on the use of defensive and/or punitive force, use their coercive powers to benefit some businesses and individuals at the expense of others, create monopolies, restrict trade, and restrict personal freedoms via drug laws, compulsory education, conscription, laws on food and morality, and the like. The embrace of unfettered capitalism leads to considerable tension between anarcho-capitalists and many social anarchists who tend to distrust the market, and believe that free-market capitalism is inherently authoritarian.
