You might do well to read some Howard Zinn for some history on the topic of egalitarian communites being replaced by industrialized ones. In his most famous work, A People's History of The United States, Zinn doesn't specifically argue against technology or "progress" but argues against coercion in its name.

He makes the point that many historians in the movement of early relativism (1920s-50s) excuse past atrocities, such as the genocide of Native Americans, in the name of progress. That is, they excuse the plight of the workers in the industrial revolution, the extermination of entire cultures and the colonization of much of Earth as being regrettable but necessary for "progress".

He also notes that many of the native tribes of America and Africa, although occasionally waring, were also generally egalitarian. Let me just pull out my copy here aaand:

In the villages of the Iroquois, land was owned in common and worked in common. Hunting was done together, and the catch was divided among the members of the village. Houses were considered common property and were shared by several families. The concept of private ownership of land and homes was foreign to the Iroquois. A French Jesuit priest who encountered them in the 1650s wrote: "No poorhouses are needed among them, because they are neither mendicants nor paupers... Their kindness, humanity and courtesy not only makes them liberal with what they have, but causes them to possess hardly anything except in common."

...

All of this was in sharp contrast to European values brought over by the first colonists, a society of rich and poor, controlled by priests, by governors, by male heads of families.

...

So, Columbus and his successors were not coming into any empty wilderness, but into a world which in some places was as densely populated as Europe itself, where the culture was complex, where human relations were more egalitarian than in Europe, and where the relations among men, women, children and nature were more beautifully worked out than perhaps any place in the world.

The current print of the book covers American history through the 2000 election.

Howard Zinn has done some great work. A while back, I listened to audio recordings containing parts of A People's History from ResistanceMP3. (It also has a lot of other interesting speeches and anti-brainwashing stuff if you have a lot of time to waste listening.)

The model of the Iroquois sounds like an ideal example if what the less wasteful, less greedy, less destructive, and more sustainable society of the future might look like. The closest thing I've personally seen have been some of the anarchist communities I've come into contact with; though of course, living under the claws of the Empire makes it more difficult due to the constant external pressures. Still, despite all the opposing cultural and legal inertia, they manage to pull off a microcosmic version of the collective vision quite impressively.
