That is low. A good formula would be to treat their stay as if it were forced employment. They should be pro rata'ed 3x the annual median household income annually (since it's a 24 hour a day commitment). And pay tax on it. It's still kind of unfair for a rich person but rich people don't usually get caged unfairly. Maybe some danger pay too if that's a factor.
