For humanity? It is the same reason most of us don't grow our food or make our shoes. Specialization makes a lot of sense. Western tech wouldn't have been able to grow as fast if electronics manufacturing were not concentrated in China. It is (was?) a win-win.

[TheOtherHobbes]

One of those "wins" was based entirely on toxic wealth hoarding by financial elites, which is why we are we are, with the flailing remains of a US government taking a hatchet to science and education while infrastructure crumbles around it, and climate change alternately floods and burns prime real estate.

So in reality, not so much.
