>It's traditionally not made up of adult children who are unable to support themselves. Instead it's made up of adult children supporting parents in their old age. This does not necessarily mean the parents are supporting their adult children directly, it also means mutual support. An example: Parents will argue "Why move out and pay a lot to a random landlord when you're welcome here and can save money?". It is not a free ticket to freeload, the child is expected to contribute in some manner to household (Pay rent, split bills, help with chores etc.). Parents from these aforementioned backgrounds actually encourage children to stay as long as they want, or at least until marriage. It is not seen as shameful that they're past 18 and still at home. I'm not arguing that economics don't play a factor, but I believe that's only part of the reason.
