There is a different dynamic that is taking place with boomers. The thought process is that they spent their lives within the system. For them, it is largely too late to start over from scratch - they have had the carrot of retirement dangled in front of their noses for 30 odd years, and the last thing they want is for someone to snatch it away from them now.

This isn't to say that it is impossible for people to change their minds - it is just that they have much more of a vested interest in making sure that the status quo continues at least a bit longer - at least as long as they are still alive.

I just skimmed the home page at http://www.thezeitgeistmovement.com/, and it sounded reasonable until I got to this part:

For example, many people are worried about population growth on the planet, while very spooky comments by despotic figures like Henry Kissinger claim that some kind of "reduction" is needed. This is, of course, very scary. However, the real question remains: Is population growth really that bad? The answer is that from a scientific perspective the earth can handle many, many times more people if need be, once high technology is harnessed. 70% of our planet is water and cities in the sea (one of many projects by Jacque Fresco) are the next step. In turn, education about life operations will inform people as to the ramifications of their reproductive interests and population growth will naturally slow as people begin to realize how they are related to the planet and its carrying capacity.
