Hawaii. A small group of islands in the middle of the Pacific Ocean. A place that probably has to import 90% of the goods and materials they demand. Does anyone really need an expert to tell them stuff is going to expensive there?
I read the headline and thought "no shit, they're an island thousands of miles off the coast."
I grew up in a mildly remote area off the usual trucking routes (2-lane highways connecting it north, south and east that washed out occasionally during winter storms) and prices were expensive even there because everything needed to be trucked in. I can only imagine the import costs in Hawaii with everything arriving by boat or air from overseas.
