In the meantime devout evangelical Christians are getting married young and having lots of kids. I think this is for two reasons:

1. They have a priority/value system that isn't completely based on shallow factors like income or appearance. Yes, money, fame, good looks all still matter, but much less so in these communities (remember communities set the standard for value judgements), and they also extend their values beyond this to include religious and character-based value judgements.

2. Sex outside of marriage isn't an option and raising a family is the goal, so couples often marry young. This does three things: (A) if you can't get your "fix" until you're married, you're more likely to keep your standards reasonable so as not to remove yourself from the game, (B) if women marry young, they're less likely to be corrupted by toxic femininity in the culture today, and once they have kids, that will be their focus, (C) if men marry young without many (or any) prior partners, they're more likely to remain faithful and be content with what they have.
