Raising kids is the "default" choice. More than 50% of people do it. Getting rich or traveling for your life are much rarer, hence more interesting
Edit: ah yes downvotes. Think about it this way. You meet someone with 6 fingers on each hand, kinda interesting right? Minutes later you meet someone with 5 fingers, also interesting?
Having kids? Probably not. Raising them? Probably yes. Same with fingers: having them is more interesting if they can do something novel with them (say, play an instrument). But this being HN, I know plenty of people that travel a lot (no idea if that’s typical).
