Nolan will end up a ward of the State of Ohio once his parents are too old, deceased, or he commits an act to bring his person to the attention of government/law enforcement. He couldn't hold a menial dishwasher job in an assisted living facility for the elderly. A job presumably requiring he do little more than show up as scheduled and wash/dry dinnerware (to acceptable standards of cleanliness..). Depending on the scale and finances of the facility, he may not have even had to actually do much handwashing (think restaurant-level dishwashers or three-step sanitizing solutions).
