Why a restored Kidō Butai still loses the production war

If the Kidō Butai returned after Midway with three times its original strength, how would the Pacific War change?

There would be more and larger naval battles, but the arriving Essex fleet would still give the United States the long-war advantage.

The scenario assumes that aircraft and aircrew return along with Japan's carriers. A much larger restored force would require the United States to fight further carrier battles, potentially on a greater scale. The Essex-class construction program would still be approaching service. The prediction of eventual American victory rests on that industrial advantage surviving the imagined change at Midway.
