That's exactly how deindustrialization looks like. Efficiency goes down because nobody knows how to build ships anymore (metaphorically speaking), so more people are required than before. A lousy analogy: think about history of agriculture mechanization but in reverse: the less mechanization the more work needs to be done manually again and the machines that are still in operation are harder and harder to operate because spare parts and technical expertise are getting harder to come by.
