"SEATTLE (Reuters) - Boeing Co said on Thursday it will move the rest of its 787 Dreamliner production to South Carolina in 2021, a cost-cutting strategy that raises questions over the future its giant Everett plant north of Seattle.
...
The earlier decision to
move some production to the non-union state of South Carolina was the culmination of a years-old board-led
strategy to reduce reliance on Washington state, where Boeing has had stormy relations with unions in the past.

South Carolina offers cheaper labor, and the largest 787-10 variant cannot easily be built elsewhere due to its size."
"In the past two weeks,
a series of new problems emerged with Boeing Dreamliners made in South Carolina. Several of them have triggered a grounding of eight 787-10 jets by Boeing and
a Federal Aviation Administration review of manufacturing practices at the plant.
Now, hundreds of Dreamliner planes are facing the aviation safety regulator's scrutiny for various manufacturing anomalies,
Last month, the FAA proposed to fine Boeing $1.3 million for alleged irregularities at its South Carolina 787 Dreamliner assembly factory between 2017 and earlier this year.
