Generally the generation is a buy-product of the culture - one's personality is shaped by genetics and/or a very small circle of influencers by the age of 3, 5 at the latest. But a persons approach toward society is shaped about 8-18 as the child becomes aware of the impacts of technology, government, entertainment, the economy and "milestone events" (Challenger Exploding, Landing on the Moon, 9/11, Pearl Harbor, etc). The GI generation is so fun to talk about because they are a huge paradox - the same group that wanted small government and came up with the acronyms SNAFU and FUBAR in reference to government ineptitude flourished under government aid.
One could/would argue that 9/11 was "the great depression" and society/culture changed on that day. We took a very nurtured and pampered generation of kids and cocooned them even more -- like every generation, it tends to lash out and be "counter" to their parental influences. In theory, todays teens will be very pragmatic, very inclusive, and distrustful of the institutions supported by their parents. So far, the trend is hard for us to recognize, because by definition we don't understand it ( the inevitable role of the dumb, not with it, dad) but todays kids are "all in this together" in the same way the GI generation was in it together. It's just that "it" is different - todays kids grew up in such a techno life they don't know life without it. Technology to them is for "sharing" whereas we Boomers view technology as infringing on our freedoms and sharing "too much" information. Todays kids see technology as a friend forming opportunity to expand community. This generation will be the one, to quote in a new context, President Reagan "tear down this wall" and crawl out of the cocoon the controlling Boomers built around them. They will be sick of play dates and want to make their own friends so to speak. Those walls may be geographic, national, generational, racial, or the wall of the human genome. We will, with the luck of a long life, find out.
