Yes, as someone who grew up in the states I can verify that this is pretty spot on. We leave for college at 18 and that’s kind of when you’re supposed to fully step into adulthood and out of the family home.
The pandemic paired with cost of living has definitely changed that a bit. But even so it’s been an adjustment for me living in Melbourne to see people living with parents into their late 20s and to not see it as a bad thing. We are told you’re supposed to be out when you finish Uni and into your own life and being at home any longer means you’re unsuccessful/lazy/can’t make it on your own.
Add it to the list of the many absurd aspects of American individualism/work culture.
