Well, one thing for certain, we can surely say that the conservatives and the right rediscovered preemptive war and the militarization of America......then again, that's pretty much the same old crap that has been spoon-fed to scared populaces over the centuries.
From the perspective of one who has been there, that article is at least somewhat accurate. Myself and my friends were reading Mother Earth News when we were 15 years old (1968) and thinking about someday living on a couple acres with a wood stove and perhaps solar or water power and a garden. My first job was as a dishwasher in a Macrobiotic (healthy) restaurant, where I did much more than wash dishes....I learned about REAL food at the time when most people were celebrating processed quick and canned junk. We started making yogurt when I was 18.
In an attempt to fulfill the Mother Earth dream, we then moved out to the boonies in WV and TN, and lived on the equiv of about $1.00 a day for three years or so - now that's a light footprint! During that period, I worked on the invention or at least a renewed popularity of soy foods, including milk, ice cream, yogurt and more. Many of my friends from the old hippie days in the country went onto great things, including the founding of the first online communities as well as much of the software and hardware that underlies this stuff (specially, The Well in the Bay Area, etc.)
The same folks are virtually 100% responsible for the rebirth of natural childbirth, having done the science, training and evangelicalism needed to promote this. As a strange point of fact, much of this movement was born out of an anti-choice stance (a stance that the right has now claimed ). At the time, the local midwives offered "Don't get an choice - come here and we will deliver your baby for free, and we will take care of it if you don't want it".....now that is radical.
The story could go on and on, but the point is not to claim this moral high ground, it is rather to set the record straight. There are LOTS of bad folks on the left and lots of bad folks on the right - there are creative folks of all persuasions....although arguably, a liberal point of view does allow a more open mind. In the longer scope of history, the hippies appear to be an utter failure - but that really only happened because hippies sold out and also because such a movement was difficult to "mainstream" into America at the time (and probably still today).
As with any movement, a lot of mistakes were made. However, the basic ideas were sound and are still valid and do have a place in the modern green movement, namely:
1. Healthy eating - what you eat is what you are.
2. A basis of life in community - "It takes a village", etc. - we can see the truth of this statement in the VA. Tech thing.....his "village" failed to either accept or see him for what he was.
3. Renewable energy
4. The Environmental movement - arguable reborn on Earth Day in 1970....
In terms of the rich and poor, yes it is somewhat true that the hippies were largely a bunch of spoiled rich kids who therefore had the time and energy to "do their own thing". But we didn't choose to be born into middle or upper class families. That just happened to be the case, and therefore we did have more options. I would argue that many movements start out this way and then the technology filters down to the rest of the populace.
All this stuff will take generations to sort out, however that does not negate giving credit where it is due. Each of us has ALL of these points of view (conservative, liberal, etc.) within us, and part of our free will and intelligence is sorting out where each one applies. My guess is that conservatives designed better airplanes and even cars while we hippies were working with soy yogurt. Some greasers probably came up with fuel injection, while we were trying to coax more spinach out the ground, and other conservatives probably built some great pollution scrubbers while Ben and Jerry were getting fat and happy on sugary ice cream.
So there is enough credit to go around - but do keep the counter culture in mind with many of the modern movements.
