Easy to prove the "generations of parasites".  Look at the families living at Mayor Wright Housing.  Walk through and you can talk to the two and three generations who have grown up there and never left.  Many feel that they own their units and have no intention on ever leaving. 

Look at Kukui Gardens, low income housing with some folks living there and owning condo rental units.  Never having to re-qualify for entering those units 40 years ago, people have abused the system and leads to the housing shortage in Hawaii.  It is worse than rent control laws that failed on the mainland.
