I would suggest that Hawaii's strategic place in the Pacific has lead to a considerable influx of military money, military personnel and associated increase in the economy related to it
Just remember, all that "military money, military personnel and associated increase in the economy" also comes with a decrease in quality of life.
Just take a look at Fayettevlle, North Carolina. It's got all the wonderful benefits of having Fort Bragg, and yet it's one of the least desirable places to live in the entire United States. Drugs, prostitution, crime and it's entirely because of its proximity to Ft Bragg.
Having a bunch of "military money" and twenty-somethings who are away from home for the first time and have a steady paycheck for the first time could turn even paradise into a shithole.
