They do. it is said that when two people get married, they suck all the savings of the parents from both sides of the family (mostly men's side), as well as the savings of the bride/groom (mostly man), to put down deposit for one house. then it's up to the man of the house to take care of 4 parents, as well as the wife and kids. And you can imagine what happens when the man realizes the house they bought will never be finished, and is worth 50% what they bought
The parents are typically living in farming community, with old/run down houses. Which the children dread moving back to, since there is no money nor future.
