What happened to the 2200 ton boats? A series of "unfortunate" accidents resulted in sinking and insurance payoffs. The 1200 and 400 ton boats left San Diego for New Zealand where regulations were less strict.
I left the marine electronics maintenance world in May 1980 for an indoor engineering job at PacBell. My former company was purchased by one of the shipyards and became a wholly owned maintenance shop for the yard. It was purchased mostly for all of the dealership licenses for important marine electronics.
Returning to the thread topic, I suspect many businesses will succumb to loss of business caused by the vaxx only customer regulations. Dead and disabled people spend less. As you alluded, a failing business model sometimes falls victim to "unfortunate" events.
...as does failed leadership/bureaucracy.
