Most of the time the parents are to blame.  If you are raised with discipline and responsibilities, you WANT to get out of the house.  That's the problem here, those parents made it way too easy for him and now he's fucked.  I know he's 30 and he's got to grow up and take responsibility for himself but it's something he's clearly never known.  Note to all parents, if you don't want 30 year old leaches living in your basement, make sure you give them lots of chores and responsibilities.  No free rides.
