You just get taken in by life though, it isn't even about saving for some idealized retirement to me. As you age and your parents get old and you have kids and a spouse you just live less and less for yourself. You have to adopt a mental state where you feel gratification in sacrificing for others, if you constantly regret the things you can't do because people depend on you, you will drive yourself nuts. That sort of "I am a reliable provider and helper" mentality lends itself to obsessively building up a "safety net" because you can feel good about how stable and safe you make your loved ones.
