The cycle does repeat, and Strauss and Howe do a great job illustrating that what we're going through today isn't new, but the circumstances and concerns of a vastly different population with vastly different technologies are. Never before have this many people been lifted this far out of poverty. A reversion to the mean would be a disaster unlike any previous cycle. Never before have this many people believed that not only will we suffer at the hands of human governance in the crisis phase, but that we are also now approaching planetary constraints in terms of environment/resources. No one can say how true it is at this moment in time, but unlimited consumption in a finite system isn't sustainable. People are compelled to take extreme actions on that belief now, and I don't think that can be said of any previous saeculum.
I know it's cliche, but the closet example in history to the American empire is the Roman empire. As it endured through many cycles, it ultimately fell completely, and for many of the same reasons we're experiencing today. During this saeculum, America has dominated the world in nearly every aspect of civilization: Technology, Innovation, Production, Society, Freedom, Humanitarianism, but those things did come at a cost. We may have begun self-reliant, but we currently draw upon human resources around the world to sustain our advancement, e.g. Iphone. It's subjective, but I think one could argue that we've been operating under the law of diminishing marginal returns for a while, and may be entering an era of negative returns.
America no longer exists to provide you, me, our grandkids, friends, and neighbors with the highest levels of safety, security and standard of living in history. It is a means to provide the corporatists you mentioned earlier with those things. Now that we are reaching a sufficient level of advancement where they may not require the productive efforts of many Americans, or even other populations to ensure their security, they must address the issue of "useless eaters". America, Western nations, and their ideologies are being dismantled. Immigration, reduction of freedoms, destruction of culture, civil unrest, inflation, taxation, household and national debts, sustainability efforts, and engagement in conflict are the attempts and methods being used to level the playing field.
Perhaps our grandkids would stand on a holodeck one day, but it won't be as Americans, it'll be as members of the United Citizen Federation. lol.
