Still really defensive and silly.
Yet you didn't answer what happens with many of these elders. Do most of these childs, that were kicked out at 18 (without a home or a job to go) or had to pay rent+bills (meaning spending most of their salaries) to their own father to stay in the houyse they lived until two days before, take care for real of their elders?
These parents were threatening their children with either you pay, or you are getting out (which means you risk being homeless). Even leaving aside the ethics of doing something like this to someone you care deeply, how can the children then not remember this behaviour when they will have to support them?
Or are elders left on their own because nuclear family and independence is put above everything else? I really struggle to see how someone who was kicked out forcefully as soon as 18 (just so parents can go vacationing), letting them accumulate huge debt (even when the family could have helped to save for their children's family just by being less egoistic), can then be happy when taking care of their elders in 20 years.
I mean I understand families where they can't support any longer their son (because of unforeseen financial reasons), but if you have the possibility why keep all the money for yourself when it can do good for someone you care? Are you earning money just for yourself? Then why build a family if you don't want to share your earnings (in part and reasonably) with family members?
Then just live for yourself and with your partner, cutting ties with other family members (aunts, uncles, and especially brothers and sisters which you will hear once every six months) and you can keep all the money for yourself without having to share with your offsprings.
Even the paying rent doesn't make sense. I would understand the bills (it happens also here in my country seldomly especially if the family is not rich or one of the parents died), but what are you making pay to your son in the case of rent? The house is yours (or if you are renting you don't pay something more for letting your son stay in your rent) so if your son already share the bills with you, you are not spending anything more than you would spend if your son wasn't there. Do you ask your relatives staying in your home to pay you just for the privilege of staying in your house? I mean doesn't just feel good to have a relative with you (and same for children) and that's repayment enough as long as they don't abuse it?
Leaving home as early as possible is great, and kudos to everybody who manages it, but threatening your child as soon as they turn 18 with: "pay or get out" (and parent doesn't care if you end up couch-surfing or homeless) is something very worrying. I mean I left for my university to study in another city for 3-4 years and come back to my parent's home after that, and many do the same here, but I don't understand what would be wrong if a parent partially supports their children or the stigma around someone living at parent's home without going to university.
I mean I'm scared of a society that reasons like this. And if you don't see what's wrong from an ethical point of view in the threatening a close relative with pay or get out of my house (even if it means he will live like shit ammassing debt or living like a homeless) I don't know what to tell you. If someone manages to afford leaving home as early as 18 all on their own, it's great and he deserves all respect, but a parent threatening their just-turned-18 child: either you get pay or get out (no matter where you end up or if you won't be able to save anything for retirement), is disgusting from my point of view in any decent society. Without even considering the aspect of why then the son would feel obliged to take care of their parents when old.
But I guess each country has its own ways. Personally I will never understand how someone could let his own blood live a terrible life (get out or pay now and give up anything so that you can't save something extra for retirement) and just hope that this tradition of threatening your 18 years old children and selfish ways never comes/spread to my own country too much. I will just make peace with the fact that being selfish and not value family members over silly money and vacations is a widespread thing in other countries.
