I assume you are American, and probably not Hispanic?
Because these assumptions are extremely cultural.
Anyways, for white Americans "Self-sufficiency" (or Self-reliance as Ralph Waldo Emmerson called an extreme version of it) is an old Puritan value, like hardwork and lifelong monogamy.
Not just cultural, but also time sensitive. If this were even 10 years ago then living with your parents would seem like weird, but today? Understand why it would still live at home or live with a person or multiple people even
