"Going back" in this context does not refer to technology; it refers to going back to a 18/19th century libertarian economics ideology, which libertarians currently espouse doing.
I agree about what the problem is. I see the solution as more government, not less. Those who benefit from the greater efficiency of automation, must in the future be required to pay for it, instead of getting off without paying, as they do now. That means those who continue to work in manufacturing and service industries need to be paid more for fewer hours of work. This takes "minimum wage laws" to a new level, applying it to all of labor. That would make "labor saving" meaningful, instead of just an excuse for the wealthy to make more money. The new professions may not fare well, if the people can't afford to pay for their services and products because they are unemployed or working 40+ hours for too little pay. I'm not sure what professions you are talking about. We will still need people to produce what the people need.The reason the Civil War cycle was as short as it was was because the advances of the industrial revolution put so much pressure on the generations to change their lifestyles. Change became inevitable. We are seeing this today with the automation of society in this information age. There is already less need for human capital in manufacturing, and we're beginning to see less need for human capital even in the service industry. This is a good thing, yet we're still trying to keep the old model afloat with standard 40 hour work weeks, artificially created jobs that are often wasteful, minimum wage laws that do more harm than good and a bloated government that is increasingly reliant on debt to fund its aging programs. An adjustment has to be made. We shouldn't worry too much about the loss of jobs. Freeing us from menial tasks is a good thing. Lost jobs will inevitably be replaced by newer and better professions that will advance us further than we can imagine. This will happen naturally, without government intervention.
As for debt paying for aging programs, the programs are no more "aging" than the capitalist system is; it is just part of a society that is more advanced than a cut-throat 19th century libertarian capitalist one. The rich and upper middle class just need to be taxed more, and that will handle the debt as it did under Clinton.
Our hero generation is not going to be a generation of entrepreneurs; though it will be in part. We won't be going back to libertarian economics, but forward into green economics. Green values will bring more freedom to more people. Freedom has many definitions, and is not limited to freedom from government restrictions on entrepreneurs; although that's what libertarians focus too much on. Freedom for the working people from economic tyranny and bosses is far more significant than entrepreneurs "freed" from government oversight and taxation. Until such utopian time as people with money are completely well-behaved and generous, government will need to be used to restrain and direct them so that they do not oppress the people, as they still do today.It's true that fourth turnings, whether they be privately focused or publicly focused, are always periods of a high degree of civic mindedness (even when the hero generations are entrepreneurs) and increasing authoritarian government control. It's a necessary evil, it seems. While I don't condone all of Abraham Lincoln's actions during the civil war, it's pretty clear that his vision for the future (end the spread of slavery) was the morally correct one when compared to the south's vision for the future (spread slavery to new states). As they say, the road to hell is paved with good intentions. Nevertheless, if faced with a societal problem, it has always been my belief that the solution that offers the most freedom to the most people is the one we should work towards. Sometimes, I admit, this is impossible, and we may have no choice but to pick the solution that offers less freedom. But we should only go that route if it's the only good option available. Perhaps Lincoln thought this too when he instituted the draft and declared martial law. Nevertheless, his overall goal was to bring freedom to more people, so you could say he was justified.
