Well Brad, I did a poor job of describing what it is about, the authors claim that this is not about politics and for the most part, that is true, (although their leftist ideology shines through in almost every thing they write). They try to show what they call alpha voices and how those voices change the culture but rarely get the recognition and very often are killed for their point of view. Alpha voices can be very good or very bad, or anything in between, (think Jesus, good alpha voice and Stalin, Mao, Hitler as examples of bad alpha voices).
Since our form of government is relatively so new, there is not much covered about that difference. The me cycle is all about big dream, big goals, (the upswing) and selfish desires (the down swing). The We is all about taking care of others, self sacrifice, (the up swing),controlling others for their own good, (the down swing). When you get past their gushing over John Lennon's Imagine or FDR's attempt to save us all, you can see some cyclical swings in the culture.
I see our culture as having a left bias; our pendulum never seems to go as far back to the right and always seems to go farther to the left with each pass. It is almost like the pivot point is being tilted to the left every year. If you have ever been on a really cheap swing set, that is not anchored down well, you keep going more to one side than the other until that pivot point goes to far, then you crash hard. (I got a broken arm out of that lesson).
That particular reviewer was wrong about one little part. They authors claim a 40 year cycle from we to me, 80 years from ME to ME or WE to WE peeks, offset by 20 years. The rest seems pretty close to my reaction. It is interesting from the stand point of 3000 years of a number of people or cultures I have never heard of, listed in the 80, (give or take), year cycle of the peeks. First the We, for 3000 years and then the Me's for 3000 years. I am struggling to finish the book but they are about to embark on the next few cycles of both. If I can get through it I will let you know how this country will end according to these two.
