Copying from others is part of learning. E.g. US copied jet engine technology from an inventor in Britain...

Actually not easy to copy as the jet engine turbine blades require very high precision.
Any imbalance will result in vibration when the blades rotate at very high rpm.

The R&D into the fabrication processes (material science), machining and subsequent mass manufacturing will thus create lots of high-paying jobs.

Making aeroplanes requires a lot of supporting industry to manufacture and supply materials and parts. The whole supply chain creates many jobs!

China is latecomer to the high-end industries, but it is catching up.

Eg. High precision machining:


Engine bearings with 50,000hrs lifespan:
