1) Better family planning:
I haven’t seen a county breakdown, but statewide the largest component of population growth is “natural growth” in other words local people having babies: 6000 more babies are born in Hawaii every year than the number of people who die.   So let’s start encouraging people to have fewer babies.

2) Aim for higher value tourism
As you suggest: don’t entitle any new resorts.  Make an effort to persuade the visitor industry to only develop high-end products: low-rise, high-quality, low-impact, high-design buildings, for low-volume, high-spending tourism.  Get a bigger bang for your buck.  Encourage hotel owners to develop long-range plans to tear-down old hotels as they age and rebuild for this smaller footprint, higher value market.  We have to move away from mass tourism.

3) Plan for high-value employment
Encourage more filmmaking and education
