I guess my brother has been a NEET most of his adult life. He's been in jail, rehab, or living at our parents' almost since he was born. He's occasionally had a job, but probation made that hard. IIRC he had to call up his probation officer every morning to find out if he had to drive a county over for a random drug screening that day, which would eat 3+ hours. It's hard to hold down a fast food gig if you can't plan your hours a day in advance.
