I think a lot of it has to do with being a blissfully ignorant kid. And I think a lot of the problems we see today is people grew up but remained blissfully ignorant.

There's loads of problems and frankly the old refrain reads true "there's nothing new under the sun" things change, the biggest recent development was social media, but that basically just exasperated social problems that already existed. Society just hasn't moved about to figure out how to deal with it yet. There's wars drugs corruption crime and it goes in cycles.

The epic cycle. The young men have passion, they go to war, they die, the survivors are strong but understand the folly of war, they build a peaceful world and they have the knowledge of the horror that man can inflict on man and have no desire to inflict that horror on others.

The next generation grows up in a wonderful era of peace and comfort, spared from the ravages of of war and the true depravities of human strife, but then just as assuredly as the older generation dies, they miss out on the hard earned wisdom about life and what really matters that comes to them only when they are sitting in a foxhole covered in shit and blood and death.

These people are smarter, they're more open minded, they have a creative spirit not crushed by the evils of the world, but they lack the perspective of time, they create a nicer world that is better than the ones their parents left them, but they fail to deal with the growing resentment of the youth, they lack the normal human experience, one of strife, and war, and they yearn for it just as a dog yearns to chase a squirrel. Eventually the older generation will allow for frivolous and pointless concerns to take the way of what really matters, whether that is one generation or two depends, usually the generation after the war understands at least on some level the horrors of it, but the last people who truly understand are dying now, Vietnam was perhaps one of the last truly terrible wars to hit the public consciousness at a scale large enough to make a difference, but even that effect is dwindling.

Another big war will happen as they always have and the cycle will repeat again. Humans will build something. Fight with other humans. Destroy what they build. And build again.
