Oh man. I visited there in 1974. Tortola is really unusual. Most of the locals live modestly, many of the houses are simple, clean, while a small percentage represent wealth. "Everything is gone" I would interpret literally.
Meanwhile Tortola is a hub for all kinds of anonymous corporations, brokers, 'Pentagon Papers' types of offshore law firms that conceal huge, unimaginable, world-class anonymous fortunes. I saw one British lawmaker just now called for finally shedding some light on these lawyer's files and the shadow corporations as a reciprocal gesture for the assistance GB is sending. (Tortola is a British Overseas Territory). If any of that economic activity became subject to local tax, the 25 thousand or so citizens could have their homes replaced immediately.
