Yeah, I agree. I think we're deep into a spiritual crisis, a crisis of meaning. A lot of people are blind to the trend because those aren't easy things to measure.

But if you're single, isolated, on dating apps -- or maybe caught in an unfulfilling marriage commuting from the suburbs to a job you resent -- there often doesn't seem much point to your own existence. Everything has been stripped of its meaning.

The spiritual crisis also explains why people aren't having kids. If there's no point to anything, why go through all the work and hardship? Parents often want to bring more happiness into the world. But if you're deeply unhappy, the logic changes.
