OHA is not issuing a neutral or objective report and nothing they say is in anyway new.  They are looking for PR and a way to distract the population from the criticism they are facing from the Hawaiian community.
The romanticization of ancient Hawaii is simply not accurate and no, Hawaiians were not automatically doing well then.   Hawaiians at the time of contact complained about the endless wars and high rates of death and destruction due to wars between chiefs.  Also, most Hawaiians are doing very well and I know that job preference often goes to Hawaiians as every wants this population to prosper.  Most are. As for more Hawaiians in prison,   um..Might it be because more Hawaiians commit crimes?  Check the stats.
