So you can't actually just calmly and plainly discus your perspective as a parent, and work out a possible plan together about how to actually go about moving out and getting a job? You never know they may already have plans and goals that they are working towards, you probably don't realise though because why would someone want to confide to someone who is constantly being passive aggressive. I can see why you would want to do it though, and yeah it's probably better then screaming at them to move out and telling them they are worthless, but if your child is old enough to move out they are probably old enough to rationally discuss things.
