The future to any long term economic success in an area, and more so in Hawaii, is Jobs, quality jobs.   Attracting the right type of skills takes more then just nice weather.  There are many places with great weather that have no viable economic future like Haiti, Puerto Rico, Mexico, etc.
Having worked years in silicon valley in Cal. and retired years now in Hawaii, I see the wonderful things Hawaii offers.  I also see the anti-business, anti growth, anti mainland, lack of leadership (rail expenditures, 3 years mess with the police chief over a mailbox) and other issues.  Hawaii is always ranked near last in being business friendly.   There seems, at times, Hawaii wants to stay the way it has,  I hear a lot, the phase, 'that's the way we do things here'.
