Actually, I would say that no one really believes in a benevolent king or millionaire, nor ever has. The majority of people are either too busy to think about or too realistic to fall for the fact that there are many humanists among the established structures. We all know that grown structures tend to want to preserve themselves, we ourselves are no different. If someone were to ask us to give up the family or professional advantages we have created through relationships, we would say "no" to that too. Why give up something that took a long time and a lot of energy? I see it that you speak of a cultural phenomenon, since it is ideal figures from film and cinema and the media in general who portray a good-hearted ruler. But surely these humanists have existed and will continue to exist. They are the bright exception to the rule and their radiance and influence should not be underestimated, precisely because they represent a minority and can move a lot that the masses never moved or aspired to, but merely imitated or followed in parts. So now the uncovering and denigrating of black sheep, capital locusts and so on belongs to the good tone of investigative journalism, just as the reporter wants to report about it when something good happens in a society.

Since we live in an age of great scales and central elements control people's destinies, there is probably no really good and plausible way to turn a central power structure into a decentralized one, except to make global peace and allow local solutions to energy and supply issues to evolve. The one often contradicts the other and so over the centuries we experience a wave movement that sometimes expresses itself in conflict and war.

Capitalism has many downsides. But without this form of economic activity nobody could afford a health system and people would have to pay their doctor's bills and operations themselves or die or remain ill like before.

In fact, I would like to contradict you repeatedly as far as the faith of the populations in benevolent kings is concerned. Much more is criticized, questioned, demonstrated, researched, published and what the classical media no longer produce is now taken over by the citizens themselves. But the question is whether the citizen is really so much better than what he reproaches the rulers for.
The Internet age is just like the newspaper and television in its infancy. People try themselves as journalists and television makers in all kinds of fields of interest and learn that television makers require certain professional qualities. It's interesting to see how dilettantism alternates with professionalism on the channels and people who really want to make quality realize how expensive it is. Not so much in technical equipment, but in time. So those who have this time live from the goodwill of others who still earn their own money in classical works. Most of it is uninteresting and boring or very stressful and full of time constraints.

I suppose about five percent of the population manages to make a living from their creative ideas and designs, the rest would like to, but can't. Nevertheless, we have much more freedom than people had in the Middle Ages, and perhaps much less freedom than people had in the days of hunter-gatherer communities.

Inasmuch as you know a charismatic and kind-hearted both immaculate person, I would suggest that you support them as much as you can and support their influence in spreading it. In fact, this is no easy question: Who is such a person? Do we know him personally? How can one even judge such a person? I suspect that people who are not guilty of malice and other vices could step into the light all by themselves and be supported by the masses, because what is real and true is actually much more interesting to support. It's a personal question of focus.

You're addressing fundamental questions, I think that's necessary. On the other hand, it distracts from detail. These details are often very interesting, such as organizing democratic structures differently, for example through systemic consensus. But things first have to be put into practice and you have to report on them. Only companies or associations have practical examples to offer. Such examples can be researched and disseminated as examples in a publication.
