@pariston_hill basically, japanese baseball boys train like they are in the military and they start from(some even before) elementary school.
Like, I'm not kidding, it's "if you don't puke, you didn't work your ass off enough" kind of training. And then of course, the society being as it is, does absolutely nothing after essentially taking away the childhood of many, many young man. Just one of the many, many issues that plague the oh is everywhere Disneyland here? and sterile on the surface, oh great Japan.
Anyway, regarding your other point, you aren't wrong per say that power makes right doesn't necessarily solves societal issues but unfortunately, the medium being what it is meant that it was never going to have a resolution on that level of depth.
Whether power makes right solves societal issues depends on where you are coming from. Because power often equates to wealth and influence(and in this case, talent too) and when that is used on said societal issues, then it is hard to argue that it won't be able to resolve said issues than the glacial pace it would otherwise be at. A species that is capable of space exploration should by all definition be able to close the cracks in their society......right?
Except not really. They won't. Is it then, because mankind is divisive so there's no real progress? But mankind can be united when there's a need to which then brings us back to the same old story. It's not that power makes right doesn't resolve societal issues, it is just that not enough people in power see anything wrong. That was the case a thousand years ago and it'll be the same a thousand years later.
We are intrinsically selfish beings but JUMP and collectivist cultures, not that they are wrong (this is not what this is about) wants the individual to think otherwise to an over-romanticized extent.
Why is the knight that punches the evil demon lord always an upright and morally honest person? Why is it that 2000 years later, we still write the same type of stories that then goes on to still become popular? The hero needs to be kind and needs to do it for the greater good when he has power/so that he can be more powerful but that's the very opposite of how people in power from the past and present really are. I mentioned JUMP but honestly this extends to every culture everywhere. There's no "god in the sky with their scales of right and wrong" that will magically come in and fix everything for you just because you are a nice person. But if you really want there to be one, then that's the very same society that has conditioned you to think this way.
People tend to believe that the idealized hero is the one that stands at the top and is powerful enough to do good that will have a large influence on the world but fail to see that such heroic narratives exist for the underlying reason to create order in an otherwise chaotic society. We think we'll be a Goku but really, the whole point of it is there's no Goku and the world only needs a Yamcha/Krillin or whatever the yes man character is that'll be there to support causes of "greater good".
This is not a Japanese thing either. We see it everywhere. There is no greater motivation than faith (well, baring starvation) and there is no tool more useful than instilling the importance of virtues and beliefs into an individual that would define them so that collectively they move to create order/chaos/start a religion, you get my drift. I call it tool but that's crude. I can't think of a better word now.
Anyway, this is terribly off topic but I just want to say that pretty much all of JoJo characters become so op and powerful with their stands in the end so it circles back to the fact that yes, in fact power does make might even Jojo. I know not all of them but most of them enough that, even if it might be a bit shallow to say so, it boils down to who has the most broken/powerful ability.
