Mobility comes to play. Lots of time people have to move out from their family home because they don’t have a job in local market where their parents lived. Second thing is that they might make much more money if they move out. Which might be much more beneficial strategy - when their parents get sick and need financial help even if they own their primary living space and don’t have to pay rent - than staying and getting what local market gives.
