I've no objection to my kids living at home, and there'll always be a place for them here. I charge them rent though - 33% of their gross pay. Not cause I need the money but because it allows them to afford to move out one day. In other words their lifestyle has "rent" built into it. In other words I'm happy to offer a backstop. I'm less happy for them to simply ignore "becoming self sufficient adults" just because it's cheaper to live at home.
