A benevolent dictator is obviously the best form of government.
The trick is, who comes after me? My sons? Someone I groom? The first one works out fine but dynasties are fucking disasters.
The 'problem of succession' has never been truly solved in all of human history.
Save that of the solutions that are called democracy and/or republicanism. But even those aren't perfect because they breed a particular class of lifelong corrupt-as-fuck career politicians who themselves pass power on to their biological offspring.
Every time I go through Roman history, I always end up thinking that the Emperors should have appointed the best man for the job to succeed them and not just their sons. This happend a handful of times but not nearly enough.
As great as Aurelius was, and even though he was not handed the throne through blood, he still ended up putting his shit-bag son up for the throne much to the detriment of the future of Rome itself. I've read his meditations. He was a smart dude who probably should have been Emperor and whom deserved his throne, but he still went with blood in the final analysis, just like Augustus did.
And honestly? It makes sense to me why this happens. We all work to improve ourselves and our families. Even the most benevolent of us do this. We are hard-wired to believe in our own children. But it's also almost biological why we, even as benevolent dictators, each of us might pick our own blood to succeed us even when we might have 2 or 3 or 4 friends whom we know would do a better job.
It plays into our females as much as anything if I'm being totally honest. We want the absolute best for our girls. That's what makes us good men in the first place. But it's also that which makes us sycophantic to our own bloodline because even if we don't know it, we know that the females tend to carry the bloodline. Maybe not the name, but the germ cells. This is why females don't go to war. They are simply too valuable to risk like that.
No matter how much sense we can make between each other intellectually, biology will fuck with our heads.
We want to groom and make someone our chosen and rightful successor, but we also know that the amount of power and wealth we are handing over is so insanely immense that we MUST keep in in our own family so as to fulfill our biological duty to provide for those with the most similar DNA, the females included.
We were biological creatures long before we were sociological ones.
