Maybe deep down humans feel that they're at evolutionary dead end and decide to off themselves as a society? I could easily see why today's western society (and possibly others as well) may be far from optimal. Yet I'd prefer to try to fix it.
What is funniest, people advocating for "progress" etc frequently are those who have no children. Although old good "you're not grown up till you got kids" outlook is looked down nowadays, I can see why it'd make sense. If you don't have kids - you don't have skin in the long game. Nor experience what it's like to play in that mode. I wonder how the world would change if we'd only allow people with kids to vote and/or participate in politics.
