When interacting IRL with people from all parts of the globe a common denominator of the generally dissatisfied is where they're from and alarmingly the states just doesn't hold up.
Again, nobody is "happy", everyone is only pretending to be happy. Everyone knows there are too many people, not enough jobs. Everyone says he hates his job, yet does his best daily to prevent any newbie from being recruited, anyone from taking his place, even if it's a shity place. Everyone criticizes the boss in front of his colleagues, and criticizes his colleagues in front of his boss. And the boss knows it well.
Life is war. Everything is an instrument to wage war, words, feelings, hapiness happen when you succesfully dominate , kill, when you see others fail. Anger, frustration, sadness happen when you fail to dominate, are dominated. Hope is when you envision yourself or you offsprings dominating others.
There is no way mankind can last forever, our so called intelligence, consciousness -of being animals- are only other weapons to wage war against others.
