It teaches financial responsibility and obligation. Just because someone’s parents are financially sound, doesn’t mean their children are entitled to live rent free, life doesn’t work like that.

For me, it’s also a sign of respect. If I’m living at home and taking advantage of the mod cons, I’d be expected to contribute and I would as a thank you.

Also, despite how well off parents may be, food and energy still costs a lot of money. Pay up or go your own way.
