I know a lot of people who spend their money on experiences because they genuinely believe they won't get a retirement, so they might as well enjoy their life while they can. I'm part of this group. I don't think the world will literally be over by then, but the future looks bleak. We've also been drilled from birth that you should never have a child if you can't afford it, and people are taking that advice to heart. And because you can't afford your home on a single income anymore, more and more parents are having to rely on childcare, which is itself expensive.
The issues are just compounding. If you just want to believe that everyone is too enamored by their phones to procreate... that's your prerogative, but yikes.
